Blue Sky GIS: Maps in comics: XKCD’s Actually

I’ve been looking into random Young Earth Creationist ideas, and according to the arguments I’ve seen, radiometric dating doesn’t actually work as a solid method of dating the Earth. There were many ideas that were used to prove their hypothesis, ranging from some fairly rational ones to ‘a tree fossilized by electricity to appear to be millions of years old. But there are ways around this. Let’s take carbon dating for example. The way Carbon dating works is as follows. Carbon on earth occurs in several forms. C and C are stable, while C is unstable, with a half-life of years. So all C , everywhere in the universe, decays at this fixed rate. So how do you date stuff using this? Well the trick is that new C is continuously formed in our atmosphere.

By Sam Lowry February 3, The show is well-written and acted, has a half dozen funny one-liners per episode, and delivers a weekly helping of science and nerd culture in-jokes. In a recent episode, Howard the NASA scientist erased several hours of data from the Mars Rover after inviting a woman he had met in a bar to come back to his office and drive it.

His pick up line:

Radiation is the term given to a travelling particle or wave and can be split into three main types: non-ionising radiation: essentially the low-energy parts of the electromagnetic spectrum.

The author is the creator of xkcd , a stick-figure web-comic of romance, sarcasm, math and language. He worked at NASA for a while. He uses mathematics to answer questions. The questions were posted on his website. What would happen if the Earth and all terrestrial objects suddenly stopped spinning, but the atmosphere retained its velocity by Andrew Brown Nearly everyone would die.

There would be super strong wind if the air was still moving. Buildings would be smashed. Hurricane usually killed by throwing other objects at high velocity at you. Those in basements might survive. There would be huge waves surging on the shore too. The sun would only rise and set once a year. Day would be 6 months long, and so would be night. The Earth might start spinning due to gravitational pull from the moon.

Explainer: the difference between radiation and radioactivity

Whoa, so this means there is a 0. Seeing is a function of the mind. But, yeah, the M and L cones are the only things giving you information in the foveola there are no rods there either. Color is a bit more complex.

This is sort of like how radiation makes its way out of the Sun’s core—but in the case of the fireflies, they’d die from the heat before the process got very far. Since the only light that matters is the light at the surface, we could imagine arranging the fireflies in a hollow sphere, with their lanterns pointing outward.

The best science is skeptical of itself, always examining its own theories to find out where they could be wrong, and seriously considering new ideas to see if they better explain the observations and data. Change is a good thing. Until a couple of weeks ago, the established count for galaxies was about billion galaxies.

For example, radiation can be measured in bananas, where 1 banana is the amount of radiation emitted per second from an average banana. They do actually emit radiation, because some of their potassium is radioactive “hoorayz for isotope variation!”.

XKCD does it again. Originally Posted by elf Seems to me that the physical space between time periods is quite clearly consistent from top to bottom revealing a consistent passage of time. If you think nothing is being done, I suggest getting much better informed about the rise of non-fossil fueled energy generation, about the last 50 years’ study of the science of the process, about the resistance by fossil fuel funded government officials and business groups to the funding of that research and the transitioning away from fossil fuels, about resistance to pipelines and coal burning.

You do sound like you’re not paying attention. I do pay attention to this and have done so since I hear people say that nothing can be done. I first heard that back when Letterman had a show, and have heard it since. I hear it and read it more often in the last three years than I ever have before that. If I can live in Maryland and buy one tank of fuel oil in eight years I am doing something right. I do know how to read the chart.

In , the narrator found that his significant other was cheating on him, and took pills to commit suicide after finding out. They ended up just making him poop all over their bed instead of killing him though, which he cheerfully concludes is a funnier story in the long run. In the alt text of number , the narrator claims that everyone knows Hitler was a waiter, therefore making it okay to be mean to them.

The narrator of is afraid now that they have the chance to experience something better than they have before. They compare themselves to a lion raised in captivity whose keeper left the cage open.

“Some remnants of what was probably Chinese silk dating from BCE have been found in Ancient Egypt.” Since the Shang dynasty spanned ca. – BCE, this is an actual example of Shang dynasty material finding its way to Ancient Egypt.

WonderHowTo In the wake of the recent tragedy in Japan, Southern Californians have been hyper alert to any news regarding dangerous levels of nuclear radiation drifting over from Fukushima. At this time, official statements from the California Department of Public Health and the EPA are assuaging the population that there is nothing to fear. While there has been some detection of radiation in the air, the current levels recorded are “thousands of times below any conservative level of concern”.

But despite these reassurances, according to the LA Times , this hasn’t prevented potassium iodide pills from selling out at numerous health stores even though public officials have issued a warning that the pills are unnecessary and could even be harmful. If the current levels are indeed 1, times below any reasonable level of concern, how do these amounts compare to the levels we knowingly and unknowingly absorb in everyday situations?

Everyday medical practices could be just as high—or higher—as the current detection, but an x-ray patient doesn’t beeline over to Whole Foods to buy potassium iodide pills. Munroe used the following sources to compile a radiation dose infographic that sheds some light on the varying intensities of radiation emitted from pretty common, everyday occurrences.

Before you check out the stats below, here’s some necessary precursory info: The unit for one absorbed dose of radiation is referred to as a “sievert” Sv.

Wild Thoughts from an Untamed Heart Monday, July 27, Skeptics and Deniers are Dangerously Wrong The Science Is In “Global Warming” by Fernando Agudelo There is a deceptive, disingenuous video circulating the cyber world called “What They Haven’t Told You About Climate Change” produced by Prager University, a nonprofit organization that claims to offer “knowledge and clarity on life’s biggest topics at no cost” through “awesome five minute videos” from a “conservative perspective.

Their recently-released climate change video features Patrick Moore, who left Greenpeace years ago to become a paid spokesman for corporate polluters and is now a consultant for the nuclear and fossil fuel energy industry. He told the interviewer that one “could drink a whole quart of it” without any harm.

When Moore was challenged to drink a glass of the weedkiller, he refused and ended the interview.

Radioactivity and radiation are often used interchangeably, but they describe different (yet related) processes. But before going into this difference, it’s useful to understand what atoms are and a few concepts about how they behave. An atom is the smallest particle that can be described as a chemical. Smaller particles aren’t chemicals in the same way that wheels, windscreens and seats aren.

Radioactivity and radiation are often used interchangeably, but they describe different yet related processes. An atom is the smallest particle that can be described as a chemical. At the centre of each atom is a nucleus , containing a number of protons positively charged particles. The number of protons determines what chemical the atom is. All carbon nuclei contain six protons — it is what defines them as carbon nuclei. Five protons would be a boron atom, seven protons a nitrogen atom.

The Cambrian radiation (meaning rapid evolutionary diversification) occurred approx. Mya, which puts it north of Macon in High Fall State Park. This is the first part of the Paleozoic (early animals) era.

The Difference Between Radiation and Radioactivity Radioactivity and radiation are often used interchangeably, but they describe different yet related processes. But before going into this difference, it’s useful to understand what atoms are and a few concepts about how they behave. An atom is the smallest particle that can be described as a chemical. Smaller particles aren’t chemicals in the same way that wheels, windscreens and seats aren’t cars — they are parts of them, but you need a few to make the whole.

The nucleus also contains a number of neutrons particle with no charge. Atoms of the same chemical can have different numbers of neutrons.

Some carbon atoms have more or fewer neutrons — seven neutrons makes carbon and eight for carbon
