I took the above photo today. It shows some Cumulus mediocris clouds. Medium sized cumulus. There are some people who think that these small fluffy clouds are the only type of "real" clouds that exists, and that high clouds such as cirrus or odd looking clouds like mammatus are evidence of some kind of global plot to modify the climate. Less extreme, but still overly suspicious, folk think that there are new clouds that exist in addition to the ten they were taught at school.
This suspicious was no doubt compounded when the World Meteorological Organization announced last week that the International Cloud Atlas was being modified to include...
Last year I created a physical model to illustrate some aspects of the WTC Tower collapses. The basic structure was columns connected by floors. The floors supply lateral stability to the columns, so when the floors are removed the columns are very unstable. This worked out reasonably well, and I got this nice demonstration from it:
The video of a Jet Airways flight being intercepted by German fighter jets is causing a bit of interest on social media, both due to the very visible contrails (enhanced by the video being filmed near sunset) and by the appearance of a "UFO":
In the classifications of causes of death shown in the chart above, CLRD (the red line) is "Chronic Lower Respiratory Disease", which is a combination of bronchitis, emphysema, and asthma. CLRD is currently the third leading cause of death in the US, moving from 4th to 3rd in 2008.
However the actual rate of CLRD is largely unchanged from 1999, actualy moving down slightly from 44 deaths/100,000 in 1999-2001 to 42 in 2011-2013. So there is no rise in respiratory mortality. The reason CLRD "overtook" stroke in 2008 was because the rate of deaths from stroke is decreasing faster than deaths from CLRD. Let's compare just stroke and CLRD:...
An odd theory floating around the internet is that one of Trump's secret service agents has fake hands, and is actually holding some weapon under his coat with his real hands. The evidence given for this is that the agent holds his hands in the same way for long periods of time.
He doesn't have fake hands, in fact you can see his hands move:
But he does hold them like that a lot:
(Even in the above you can see he does change hand positions, his thumb in particular.)
But what's up with the guy and the stiff hand position? Well it's actually a core...
When I first saw this it was nearly horizontal, and looked, if not a flying saucer, then at least like a flying plate viewed edge on. It's a distant sunlit contrail, often mistaken for UFOs, space junk, or meteors. So I thought it would be useful to get a sequence of photos and video at different zoom levels.
