The Day The Soviet Union Dropped A Nuclear Bomb On Its Own Citizens

The Orenburg Oblast Blast

The article originally identified the bomber as a Sukhoi T-4, an aircraft that did not fly until 1972. The mistake was obvious to me from the picture, which has not (as of today) been replaced. That is not a bomber from the early 1950’s. The bomb was dropped from a Tupolev Tu-4, the Soviet copy of of the U.S. B-29 bomber, which was used in the bombing of Hiroshima and Nagasaki.

Faking History

Romans Invade Ireland

The following is a parable about how history is written on the internet. Let’s imagine you have a web page and you want people to visit it. How could you get the history scoop of 2014? Well you could go and bribe some doctorate students, ask for an interview with a wanw professor, research an area to death and pontificate… What you don’t have time? Then why not just make it all up?!

Relativity is Right on Time,…

… Again

Special relativity predicts that a twin in a high-speed rocket, as viewed by his Earth-bound brother, will have a slower-ticking clock. A precise test of this time dilation, first performed in 1938, involves observing the frequency shift—or “ticking” change—in the electronic transitions of fast-moving ions. An update of this type of experiment using lithium ions has now verified special relativity’s prediction with unprecedented accuracy—a result that provides additional constraints on quantum gravity models.

… 2014 Takes Aim At Hottest Year On Record

Last month was the warmest August since records began being kept in 1880, the National Oceanic and Atmospheric Administration (NOAA) reported Thursday. NOAA also projected out scenarios for the rest of the year making clear that 2014 is going to be one of the very hottest years on record — and possibly the hottest.
