They are small and light like water, only a few feet in diameter and weighing less than a cup of coffee. They are so tiny, they pass through most body weight of a person before they get into their bloodstream and can no longer make any chemical changes. However, these molecules are extremely damaging to our bodies and may be able to cause damage to our DNA, or to our eyesight or brains. The most dangerous is called a UV ion, and we cannot survive exposure to the UV radiation from natural sources at any level of exposure. Since so little is known about them (and no, UV rays are not responsible for cancer), we need to be looking for ways to protect ourselves from being irradiated. This isn’t an easy task, and only scientists with a special interest in this research could be trusted not to abuse their work for nefarious ends. (For more information, see the link at the bottom of page 12 below).

The first step is to identify what the key is. It is called ionization, and the amount of ions we absorb and then emit is called flux. By comparing several experiments, we have established that only about 1-2% of the total oxygen dissolved in air is ionized, and the only ionization we are interested in is the low-energy oxygen-dioxide ion from the burning of fuel. We have measured flux by using a very accurate measurement meter. As mentioned above, we believe that the amount of oxidation products in the air is actually much larger than we have been able to measure at low levels of energy. The first step is to determine these products. We refer to this as free oxygen flux. This is measured by putting a breath of pure oxygen into a glass tube filled with air. The amount of free oxygen is called oxidized oxygen. We have measured this to be about 3 micrograms per liter. We believe that oxidized oxygen is what is most damaging to our DNA and the DNA of plants and animals. According to our calculations, that is more than 10 times higher than the normal amount of free oxygen in the air. The amount of free oxygen measured in atmospheric air ranges from 0.0 to 2.5 micrograms per liter or about two percent of total oxygen in the air. Now we know what we will need to make our detectors. Most of the common cheap detectors used for fire alarm monitoring are very similar. Most are very simple, but some require specialized parts just to make them. Our detectors are much more complex, and use a sophisticated system of metal detectors, laser detectors, light detectors, and a temperature sensor. We are now ready to begin our research. Since so much of our detector electronics is made of solid state technology, we are not worried too much about safety. The detectors we are using are made of a material that resists bending and deforming, makes it cheap, and keeps working well for years.

The next step is to identify the types of radiation that the detectors will sense. We will also need to measure the emission spectrum of the emissions to calibrate our detectors. We are using a range of values for detection levels ranging from “0” to 70% [6]. We need to be able to define the radiation frequency or the duration of any given radiation. The radiation frequency ranges from the very low frequency (VHF) to the high frequency (HF) of the band used in indoor and outdoor fire applications. We’ll be using a VHF device that emits an “0” band, which is the type of radiation that is used in fire alarms. Our high frequency device emits a high-energy ionized ion (X-rays) and short-wave radiation (e.g., UV). Our low energy radar device uses a low-energy ionized ion. Our high energy radar is tuned to the shortwave radiation (UHF) we are measuring. For both of these detectors we are using an instrumented detector, which makes it much less likely for anything to go wrong. We recommend using a dedicated instrumented detector since they are far more detailed. We have used a single, inexpensive piece of equipment over 20 years that is probably the best instrument used for the types of detectors we will need. This instrument combines the low cost and precision of an analog instrument with the speed of radio frequency (RF) measurement.

We are now ready to begin analyzing the data. First we will determine how the detectors will work under our proposed conditions. We will add a “high” to the flux number. The typical high frequency detector is tuned to “0” in the flux number, so adding a “0” to the flux number means we will hear nothing. Adding a high means that we will hear the high, and it will not cause any alarms. To get

These events occur when a huge “stomp” of the waves reaches the seabees which gives them the “feel” of waves hitting and beingreeledin. The seismic events are alsolinked to earthquakes. During these large ocean waves hitting the seafloor, the seismic noise comes far closer to the seafloor when compared to waves hitting a shore or rocks which have smaller waves. This allows them to be heard through those waves. When these waves meet with a “stone formation” at the bottom of the ocean the pressure waves can beproduced. These pressure waves push up on a small crack in the seafloor and form underwater crevices. In the pictures below, the broken seabed is at the bottom of a deep sea trench.

And below is the same crevice, but this time with two craters. We can see that the pressure waves inside the crack are stronger than those outside the crack thus creating the crevices.

Turbans and the ocean floor When a wave strikes a deep ocean trench, it produces waves ofsimilarstrengthfrom the bottom of the trench along the trench, with greater height at the top of the trench. This creates a large crevice called a trench trench mouth. This cavity is much larger than other ocean crevices and has a higher pressure than the seafloor and ground, therefore it is easier to hear. In these picturesthe pressure waves inside a tiny crevicethat is about 5 feet long are shown on the left side here. The crevice size is about 3.4 feet long.

The second picture looks at a giant crevice forming on the ocean floor. The trench mouth is about 8 feet long and the wave crevice is about 7 feet in diameter. The pressure waves were strong enough for a car to pass through.

Waves travel at about 10 miles per hour. The waves on the left side above are about100 times much stronger than the waves on the right side, about a half a mile per hour, due to the fact that the waves are running faster in both directions. You can see that a wave at 10 miles per hour would pass through the waves on the right side10 times faster as expected, but the wave on the left side would only be passed through 10 times faster due to the speed differential. When a strong wave hits a reef , the wave moves at about half of the speed of sound and the water gets rougher. This is why reef erosion and water waves occur most oftenon shallow and weak reefs. An exception occurs in the case of deep sand dunes , where huge waves are formed on the outer face of the dune. This creates a giant cavity that is about a mile in size and has a pressure of about 1,000 times greater than that of the ocean. This cavity creates a crevice that is 10 feet high on the outer face and 5 feet high on the inner face of the sand dune, making it the largest crevice formed under tidal conditionson Earth. The crevices are a sign that there has been a lot of volcanic activity on the planet. Sometimes, the surface of the surface has eroded. However, often where the surface has not even been disturbed, crevices form to let it move like one would like a sand doll. These are known as “deep crevices”. In these images and the images before them, the crevices are being formed by seismic forces. Thesoundscome from the earthquakes and the pressures of the waves in the deepest parts of the trench. The crevices are not from volcanic activity, it is the action of big waves hitting those crevices to create the crevices.

How can this be? I suspect what happens is the wave crevices were formed by the earthquake which washeard over the shore and is now being felt by the seafooms. An earthquake that is heard over a large area at once can trigger the wave crevices at the surface.

We know that during earthquakes, the Earth vibrates and the ground moves as the seismics moves at the same time. This actiondynamicallychanges the ground and the sound it gives off, allowing it to be felt through the waves. So when waves hit a crevice, they will be forced to strike the crevice in a way that causes the crevices to be formed by the seismic waves. I think the waves are creating a crevice at the bottom of the deep ocean trench that has a pressure of 1-billionpsi. To get into that pressure is to be in “tunnel mode”, where they have to change how the shock waves vibrate to keep it from breaking into pieces. Tunnels are hard to make in the ocean (but not so in the deep sea where they are made of soft water, so we can tunnel). A quake that is heard over a wide area, can create

A strange planet could provide vital clues for the nature of our own home planet. New research suggests that the very act of orbiting a star could be a crucial step in the evolution of planets. The planet is one of three planet-like objects discovered orbiting the star 2MASS J14062427. If observed using telescopes around the planet, they will help scientists better understand how planets form, and are the first planets that likely formed more than ten times away from their star. The new findings will be published in the August 23, 2016, issue of the journal Astronomy & Astrophysics. It’s a very unusual planet, and one that’s actually very common. For over eight years, scientists have been working to identify planets that are similar to our solar system as we have discovered several similar worlds around other stars. At the time, this was very difficult, as there were already so many objects already that they were hard to separate when looking at the large scale. However, it’s getting better today.

“Planet 1” (2MASS) in the form of a star, known as 2MASS 42873399, orbits in a highly irregular orbit, passing between the star three times a day. The star is in the constellation of Centaurus, while the planet is in the northern constellation of Aquila. The star is actually very close to the planet, and it’s thought that the distance is less than 400 astronomical units (AU). Image from NASA, ESA and the Hubble Heritage Team (STScI/AURA)

No further research should be undertaken unless there are good reasons to believe the findings. The new star is known to be a hot red disc, which is common for all red giants. Since the star is so close to the planet and its mass is close to that of our sun, the planet is likely to be pretty hot. This means that the planet is likely to be an exoplanet with a surface temperature of more than 250,000 Kelvin (430,000 degrees Centigrade). If an exoplanet with mass of greater than 500 times that of the sun has this extreme surface temperature, it indicates to our solar system that the planet has a huge interior. While some speculate that the sun and the planet both have a similar core, the evidence is not strong enough to support this theory.

It’s not quite as hot as that, but also not that far away. Also, when we get to worlds similar to our Earth, we will probably find evidence for the planet’s core. Then, we’ll make a better prediction; but for now, we know our Earth is very old. 3:01 PM, January 30, 2016

The duo described how their companies are in the market for self-driving cars but have been unable to find anyone that is as smart as the average human, and are in the process of building a machine of equivalent intelligence. Alibaba’s Ma then explained that self-driving cars would be much cheaper to build than human-level machine intelligence in a few decades, and are thus a superior solution to our current state of affairs.

With all of this talking about AI, it’s perhaps worth exploring other topics and areas. In a section titled “How To Deal with Deep-Mind,” Andy Weir focuses on a topic to which many people are already deeply concerned: the use of artificial intelligence to manipulate the behavior of humans. While exploring the potential value of technology to manipulate other humans for negative profit, Weir lays much more broadly on the ethical, social, and political implications.

Though this is one of the more intriguing sections in Weir’s book, it still feels like an afterthought. Worse, he appears more interested in describing science, technology, and science fiction in the style of science fiction than actually exploring the many possible uses of AI. While I agree that there surely are many more uses than just manipulating human actions and decisions, I would argue that Weir’s focus makes a very misleading reading of what is most important about current human-level AI.

What is most important about technology is about our ability to create new and better ways to use existing infrastructure, to create new ways for our current systems and architectures to work together. This is where the potential for disaster presents itself. The vast potential difference between using systems in the way we want them to perform, vs. using them to do something that’s bad for us. This is an argument that I’ve made repeatedly in my articles and writings: we need an ethical framework for technology that takes all of the potential for the bad things that can come from doing this very, very dangerous thing very seriously. We cannot get an ethical framework until we accept that the current use of AI and machines is incredibly dangerous and unethical.

“It is easy to be optimistic,” he concludes “but optimism can only lead us so far. With the right policies and the right support we will be able to make the changes we need.” I would argue that we do need to change the policies and support necessary for this kind of change to occur, but we also need to go back to the old ways, and not be afraid to make big changes where necessary, to preserve what we have (including creating a more humanized tech environment).

So, while I agree with Weir that we need to be very critical of current AI and its potential uses, but I do believe his “more humanized tech environment” is not the answer. Instead, I think an ethical framework that takes the potential benefits from the technology (as defined here) very seriously while also respecting the possibility of catastrophic disasters should be our next step.

I may not get the chance to post it in this blog until the fall, but after our last trip to Seattle, I thought it was time to get back to the blog from time to time because the weather is going to be really hot and humid in late September. So far our trip has been smooth, and we got a good feel for all the different places we ended up going and how it would be different and similar. We stayed overnight in the gorgeous Pacific Northwest town of Ballard which is a fun little town on the ocean, right across from Ballard pier. Our first stop was to go visit the Ballard Farmers Market, not my idea of a good idea, but we had no time so we did it anyway. It was pretty fun to see all different farmers with their different farm products and I’ve noticed that a lot of times people do see me at the farmers market, but I really don’t see people coming in with their kids really trying to sell them their food. After the farmers market we all went to the Cask Works on top of Pike Place market. It seems like a lot of people that run around Pike Place Market are also farmers. And I’ve also noticed that people there are selling their goods into downtown, but to me these don’t seem very different or interesting. They are kind of a lot like the farmers markets we used to get at the end of college and in the beginning of graduate school. So, Pike Place market was one of the coolest things we tried this trip with, and after this amazing trip we were looking forward to the upcoming trip. So, we went up to Seattle and took a cab back. We sat in the back seat with our bags on, had a few drinks we picked up in the market, and just enjoyed Seattle until the cab moved into a spot it was comfortable in. And then I woke up this morning to my husband having an allergic reaction to the first few drops. So now we’ve gotten back to the business we were doing earlier.

The good news is, I feel pretty good. I don’t know how we would feel if we could all get into the same bed and that didn’t happen.

I’m not crazy about the temperature in Seattle. It was right around 70 F during the night which is kind of cool, but when I have it all together, it starts getting uncomfortable. I wish I had better things to do, so I can enjoy the weather a little bit more, or just to throw on my favorite sweater and get a nice cool bath with it if need be.

The first thing we needed to do was to head to the Best Buy, and before we got back to Pike Place I did something I had really just done on last trip and I almost didn’t do it. As I was getting ready to get in the cab and head for Best Buy we realized that we need to pack up all the stuff we had been carrying into the car. We had a few bags that fit into our cars and we were all getting pretty excited when we got there to find all the packing done. And then, if we were lucky, there isn’t much to carry as we left the store.

Here we are, in the Best Buy back lot. It looks kind of dark, but we were pretty excited about going there. It took ages, but things started to look decent when we pulled up beside the building. There were a few more things we needed to try out that night. Anyway, we pulled up beside the building and stood on the side of the building to wait on the line for the employees waiting there. We looked around for like 15 minutes waiting in line for what must be like 5 minutes, but finally the waiting was over and we headed down to the back area to walk around and check out the other places around Pike Place Market. We visited the Little Shop of Art on 15th street, talked to the guy working there about some interesting art he’d seen, and we bought a coffee at the Mango Shop. We went with the Mango shop because we were a little weirded out about the Mango shop on Pike Place because they don’t make Mango flavored coffees. I also thought maybe I wasn’t weird enough about that and wanted to try and be kind of unique and different.

I have to admitwe were really turned off by the Mango shop and the kind of art on the wall in between. We took a little more time exploring around Pike Place, going and checking out all the different houses and neighborhoods around there and picking the one with the least amount of people in it. I was a little too nervous to even enter one neighborhood, let alone the other. After some exploring around Pike Place we ended up heading back to the Best Buy, thinking that we would head home later that day

The aurora’s appearance in the sky may also be visible further north, near the Canadian border.

A look at the Earth and aurora

Earth As Seen By The Moon A few hours before sunset on Thursday night, the southern coast of the United States is illuminated by daylight. The sun rises above the east side of the Earth and sets atop the West side of the Earth. The top level of the west-facing limb is nearly as high as the level of the Moon. The Sun rotates with a rate not much different from Earth’s, so the Earth does not move between two parallel orbits. One rotation of the Earth takes about 7 hours 39 minutes. This motion of the Earth is just as fast as that of the Moon and our Sun. This fact makes it possible to travel from one side of the Earth to another as we move westward. (The distance between the center of the Earth and the other side of the Sun is 93,000 miles (150,000 km). There are three primary forces that pull matter toward the central orb when the Sun and Moon line up on opposite sides of the Earth. Two are gravity and the others are the Sun’s atmosphere and magnetic fields. An object in the atmosphere (called a solar filament), for example, is a large ring of plasma around the outer edge of Earth. A small amount of matter (more than 0.5 micrometers in width) from the sun will enter the atmosphere of Earth to rise, fall, or swirl in front of and below the Sun. In this way, the atmosphere of Earth can be thought of as two big “wheels” with spokes or “ribbons.” The spokes are moving at different velocities . The spokes can also be seen as an airplane passing above the lower and upper belts of the sun. The velocity of the spokes is what causes the belt to change and the sun to appear to rotate around the center. During the early hours of December 2, the magnetic activity in the belt (called the Southern Heliacal Cycle) increased (this is expected due to the rotation of the Earth). This might happen several times before the cycle ends at mid-January. The last heliacal motion is known as the sunspot minimum.

A view of the solar wind , a fast spinning cloud of charged particles that travel backward from Earth. A coronal mass ejection, or CME, is a giant spinning, fast-moving cloud of charged particles that travels backward from Earth. Solar wind, along with two other major eruptions around the sun, are known to cause an unusual alignment of solar magnetic fields, sometimes called solar flares. This has been called a “sunspot cycle” for a series of events in the last 2,500 years called the Little Ice Age and the Glacial Maxima. These eruptions are believed to be triggered by the energetic particles from the solar corona. When the sun goes nova, the corona heats up and shoots out particles that send energetic particles into space.

A view of the Earth from the Sun This animation (below) shows how the solar wind works.

The Earth And Sun With the Sun Moving Through The Sky The Earth and the sun are constantly moving through space. This is due to the solar wind, which is like a small tornado moving backward from the sun. To take a look at the motion of the Earth and the Sun, look to the solar horizon and the south. As the Sun moves through the sky, it creates what the astronomers call a coronal mass ejection (CME). A CME usually rises in the middle of the night, travels outward for an hour or more, then turns back and sets in the same part of the sky. Each CME carries about as much energy as the sun produces in a year. These CMEs often cause changes in the magnetic field and ionosphere of Earth. As the Sun and the Earth turn from north to south, the magnetization of the atmosphere changes. As the Earth spins at the equator around its axis and rotates clockwise, the atmosphere spins counterclockwise. These forces create disturbances in the magnetic field of the Earth that may seem like magnetic storms but are actually caused by the change of the geomagnetic field. In other words, the auroras seen in this area are caused by the Earth’s magnetic field. As the sun moves through the sky, it creates some disturbances in the aurora caused by the Sun’s rotation. When we look at the Sun, we are really looking through the eyes of someone who is looking at the Earth. We can see the Earth, but not its atmosphere. The Sun can be seen in different wavelengths of light, each of which has its own particular wavelength of light. While you can see the sun in various kinds of light wavelengths (colors, for example) , the most commonly seen spectrum of light is ultraviolet (visible) which is the most powerful UV light at the Earth’s surface. While you can see several colors of sunlight and that the Sun provides many different colors of light,

(Credit: G.C.Barczynski.) In 2010, Volcanic eruption caused a total blackout in the country’s south, with about 2 million people in the southern and central regions still largely without electricity since late October. Most of this blackout occurred on October 27th, with the sun’s rays apparently breaking the water power lines, shutting off power distribution as far as 150 miles outside Volgograd, Russia. Unfortunately for the inhabitants of those areas, the sun doesn’t set and doesn’t rise for hours and hours, meaning that the whole blackout could have been averted if the sun had not interfered with electricity supply back in October. At around midnight on October 27th, at the height of a local lunar eclipse, the sun came directly over a nearby mountain range and slowly started moving eastwards towards it. (Credit: NOAA.) So how did Volcanic Eruption Doku Natakaya affect the local landscape? By providing a clear, unceasing light on what’s in store for the land. The eruption produced a thick dust cloud high into the sky. This stormy dust cloud swept across the South Caucasus, creating the same kind of dust “moss” that had previously been discovered from ash clouds. This cloud of dust coated the air and ground with layers of gray, dustlike particles. However, one area of the southern Tien Shan Mountains was completely enveloped by the clouds.

Another view of the smoke from the Volcanic Eruption. Image credit: NASA.

By some sources, this area of Tien Shan might have included the remnants of a large crater that caused the ash cloud to blanket Russia and eastern Tien Shan. Volcanic eruption has sometimes raised concerns in the Soviet era that an asteroid impact might have happened around such a nearby volcano. The same remains true today because of changes in the earth’s magnetic field and in the position of the sun as it comes closer to the earth. In the case of Volcanic Eruption Doku Natakaya, the volcanic activity is so strong, the sun’s light touches it (see this related article: “The New Siberian Volcano” (October 11, 2012), by Peter Seibel, Science in Science Books, p. 25). Many scientists believe that the Volcanic eruption will be much smaller than the Volcanic Eruption that happened in 1999, and therefore, much less destructive, though, the area could experience “severe eruptions” (meaning that the entire crater could completely collapse and spew ash far, far away). This is the image of Volcanic eruption Doku Natakaya from a May 2011 press release from the Russian Geophysical Institute. (Credit: K.N. Tsherkine.) Other events in 2011 such as the eruption of the Buryat-14 volcano that erupted at 11 am on May 26 may also play a role in the future of the solar system and in potentially creating a “ring around the sun”, not a solar eclipse, which may occur around the time of Doku Natakaya and other Doku Natakaya-like eruptions. A Russian scientist says that the future for the solar system is “unknown”. The Russian scientist is a member of the National Academy of Sciences, also known as the Russian Academy of Sciences. One of his own members called him an “obligatory” scientific idiot . Now, where is a geologist’s home?

Not even 10 feet away. And it was a fast one, too. That was a very big comet. Even so, only a few seconds of the impactor’s speed made it into the atmosphere, and only the meteoroid’s heat from hitting the ground burned the air just a fraction of a percent of the meteoroid’s weight, which is roughly as much as the impactor’s width and length. That also only caused a tiny bit of heating, and not enough to melt its path out of the atmosphere. The heat was much lower than expected, even without looking at the meteor’s color.

In the end, the impactor burned up and cooled in the atmosphere, and is likely the cause of the meteor’s speed. So, what’s the impactor’s impact on the comet? Well, the comet has been growing the past few hundred years, and the meteor impactor’s impact is what’s allowed it to grow. It’s still tiny, and can’t keep up with the comet, but it’s able to burn more, and faster, and therefore it creates more light and heat.

It gets even bigger. Now we all know that, no matter what, if a comet is going to get any larger, it can probably only do so by hitting a planet. However, that’s not much of a problem. The Comet Encke. It was almost certainly a comet hit by a planet, and the impact has likely made the comet much bigger. Maybe ten times bigger. The comet was a good ten times heavier than a typical moon, too, so even though the impactor wasn’t that high, it still created a lot of energy, including heat. The impactor’s mass will accelerate the comet up toward the sun, and perhaps some more energy will make it reach the point where it could start moving away from the sun. I’ll give the comet another try. It’s probably going to get a bit bigger than the comet would be in ten thousand years or so. I’ll say “maybe,” because the comet is a lot more of a mess than it is now, and it’s too hard to try. It could go either way very soon. Maybe it’ll become a star or a comet, and it’ll be a really, really cool object. Or it might simply have been pretty lucky, and it will burn up. But I’ve never seen one that way, and I see lots of comet burnups that I don’t know how to explain. I just don’t think anyone has.

One theory, by a man who makes a living explaining the world, for making lots of predictions in the future, is this : a comet will hit Earth the way a moon hits the Earth, on September 17, 2012, and it will grow big enough to grow into a planet, and maybe just grow further, making it really big and bad and bad. This is the most likely interpretation of the comet’s impact. It has some details that bear on this: the comet is pretty low on the solar system’s gravity-budget, and it will hit Earth on September 17, so it gets a lot of time. And even though it hits someplace on this date, this is not actually the sort of place “it has to” hit. That place may be somewhere else, or it will probably be really, really close. But, that’s enough of the big-bang stuff for now, and the next post will be about that.

The sun has lost all of its radiants due to the presence ofcarbon monoxide in the space surrounding its rings. The study also found sulfur in the magnetic field of Saturn’s gas giants, which it concluded were an early sign it was forming. The new finding gives the planet’s rings the “sine wave” look. This latest view of the sun and its planets is provided by NASA’s Cassini spacecraft and the Spitzer Space Telescope. It is the first time that scientists have photographed Saturn’s rings from above. NASA’s Hubble Space Telescope captures the view by combining multiple exposures taken in 2011 and 2012. Image: Cassini, NASA [high-resolution] Caption: NASA
