The 68th observance of the first use of a nuclear device in war is on Tuesday August 6th.

You can use this interactive Sim to estimate the effects of "Little Boy" (15kt) on your local area.

• There are presets. If your town is not on the list you can drag the map pointer to your chosen location.
• Click on the Advanced Options arrow to open it for more options.
• If you don't want to log your anonymous usage data, click on the check box at the bottom aside the Auto-Zoom check box.
• Once you click on the "Detonate" button it takes several seconds to calculate the estimated fatalities and estimated injuries.

There is also a 3D Sim. It can be reached by this link or at the top right of the 2D map: NUKEMAP3D by Alex Wellerstein
Settings are similar, one difference I found was in placing the location. Instead of dragging the pointer you had to drag google earth to your chosen location, then click on the "Place Target" button.

Top site Anak thanks have a watch at this probably one the most evil sights one could imagine
and reminds me of J. Robert Oppenheimer's quote "I am become death, the destroyer of worlds".

I am fascinated by the nuclear blast videos.

12 months of NASA’s Curiosity rover in 2 minutes

Can you believe it has been almost a year since NASA’s Curiosity rover arrived on Mars aboard it’s crazy rocket sled? It has spent those months rolling around the Martian surface, scooping up clumps of soil and drilling holes as it performs experiments. In celebration of one year on Mars, NASA has assembled a video of Curiosity’s time on the Red Planet.

Genetic Adam and Eve may have walked on Earth at the same time

All scientific evidence points to the fact that if you go far enough back, all life on Earth is related through common ancestry. Turns out that applying the same sort of analysis shows that all humans alive today are descendants of one man and one woman who walked our planet thousands of years ago.

For several decades, there has been debate about when these ancestors, popularly known as Y-chromosomal Adam and mitochondrial Eve, existed. Two studies published this week find that there is a good chance Adam and Eve may have existed about the same time, evolutionarily speaking.

Simulating 1 second of real brain activity takes 40 minutes and 83K processors

A team of Japanese and German researchers have carried out the largest-ever simulation of neural activity in the human brain, and the numbers are both amazing and humbling.

The hardware necessary to simulate the activity of 1.73 billion nerve cells connected by 10.4 trillion synapses (just 1 percent of a brain’s total neural network) for 1 biological second: 82,944 processors on the K supercomputer and 1 petabyte of memory (24 bytes per synapse). That 1 second of biological time took 40 minutes, on one of the world’s most-powerful systems, to compute.

Gary the you would be interested in this site where I get some good wallpaper material from

Yep amazing stuff Bill we were taught that all humans are born with enough brain cells that even at the rate of loss of 10,000 per day we have enough to last more than 200 years - that is if you don't lose them at a very fast rate eerrmm like me LOL!!

PS I should have said also that is for normal brain processing not in toto
