This is another of my "Doomsday Debunking" articles, using science and astronomy to debunk some of the crazy modern myths about the end of the world.  This time it's the idea that the eclipse of the sun on 21st August in the US is a "sign" that the world is about to end. If you are an astronomer or scientists you will just LOL at this for sure. But for some people this fear is like a living nightmare for them. They contact me, extremely scared that the world is, literally, about to end because of this eclipse. They probably flunked maths and physics at school and just don't have the scientific and astronomical background to evaluate it.

This is the third part of Chapter 3 of the book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab". The chapter recounts the pioneering measurement of the Z mass by the CDF detector, and the competition with SLAC during the summer of 1989. The title of the post is the same as the one of chapter 3, and it refers to the way some SLAC physicists called their Fermilab colleagues, whose hadron collider was to their eyes obviously inferior to the electron-positron linear collider.

Survey results show that workers believe the American workplace is physically and emotionally taxing, and they don't like the social environment. Since we are only now recovering from an economic malaise, they also worry about unstable work schedules. Some cited unpleasant and potentially hazardous working conditions.

Physicists from the ATLAS experiment at CERN have confirmed one of the oldest predictions of quantum electrodynamics (QED), finding the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction.

Nomophobia, defined as smartphone separation anxiety,  is when people perceive smartphones as part of their extended selves.

Counselors, lawyers and therapists are aggressively pushing it as the fad diagnosis of 2017, but what behaviors and descriptors can help identify people with high nomophobia ? A new paper compares how people considered to have high and low nomophobic tendencies perceive and value their smartphones.

No, this is a theoretically based rant about TSA. My students can get credit for reading it!

With all the tense situation about North Korea, I thought I should do a new post about the situation there. I'm doing this as part of my "Doomsday Debunked" articles I do to help people who are often very scared that the world will end in one way or another. First this is not a risk of global nuclear war. It’s nothing like the Cuban missile crisis. There we had two major powers facing each other on a hair-trigger. And each had the capability of destroying the other’s military capabilities.

Have you wondered why we can't see the Apollo landing sites from Earth? Moon is so far away that even the ISS at around 108 meters in length would span just over one pixel if Hubble were to photograph it on the Moon at its highest resolution. From NASA:

Can Hubble see the Apollo landing sites on the Moon?

No, Hubble cannot take photos of the Apollo landing sites.

“An object on the Moon 4 meters (4.37 yards) across, viewed from HST, would be about 0.002 arcsec in size. The highest resolution instrument currently on HST is the Advanced Camera for Surveys at 0.03 arcsec. So anything we left on the Moon cannot be resolved in any HST image. It would just appear as a dot.”

We know that corporations go where their market is. Whole Foods sets up shop in wealthy, progressive counties while smaller companies like Monsanto market to rural farmers. What about fast food companies? The claims have been that since there are obese people near places where high densities of restaurants exist, the restaurants must cause the obesity. Less considered is that people might move to where more food choices are and where those are dense, such as in cities, people tend to be more educated.

You may have seen this tank filling puzzle that's gone viral. But have you wondered what happens at a faster flow rate? Someone has tried it out, with a 3D printer. First though, let's look at the original puzzle. 

 Here it is.

Look closely, as it says.

Most people answer “G”.

If that's your answer too, take another close look. Many of the pipes are blocked, The line that blocks off D from C is not a mistake.

To find the real answer - well first, it looks like it's just a drip at a low flow rate from the drawing. So let's assume that..

From A to B to C is straightforward. None of them can fill before the next one.
