Batteries on concrete used to discharge

Used to be batteries would loose charge to concrete. Modern materials have solved this problem.

Re: Why the high degree of granularity?

The original design of one hour time zones meant mean solar noon would be up to 1/2 hour from clock noon, if the boundaries were evenly spaced at 15 degree intervals.. Actual initial boundaries had some locations approaching 1 hour. Time zones creeping eastward have resulted in over 1 hour difference. Daylight savings time can bring this up to 2 hours. Then China went from 5 time zones to 1 time zone and you have an international boundary with Afghanistan with a 3 hour time change. By the time we accumulate 3600 seconds for a 1 hour change (about 7000 years), we could just skip the DST change in the appropriate direction, or non-DST locations schedule a time zone change.

Re: It just costs money

I believe the shuttle flew on core memory. Very helpful with the Challenger investigation.

Big Bang or Large Bang?

I am wondering if we will need to downgrade the Big Bang (created universe and all matter we can detect) to a Large Bang (an explosion within an existing universe and additional matter outisde the range we can detect at this point.

Re: Bah!

A 2 ft by 6 ft airplane door is 12 * 144 =1728 sq inches.Say 12 psi inside and 7 psi outside, about 8640 pounds holding the door closed. A 2 ft round hatch is about 576 * Pi / 4 about 450 sq inches * 3 psi would be 1500 pounds.

Write count exceeded?

Did they check DAILY how many bad sectors they had on the SSD Flash memory? They have a limited number of writes and when the number of bad blocks start to rise you have to replace the SSDs.

Can general relativity explain the OPERA neutrino result?

Mike Schwab

Mike Schwab

Note that the Neutrinos that DO NOT change flavor arrive *AT* the speed of light.

Note that the Neutrinos that DO change flavor arrive 1 PLANK LENGTH earlier.

This is due to http://en.wikipedia.org/wiki/Virtual_particle involved in the flavor change.

The new flavor leave the area of the change at the same time as the old flavor arrives at the area of the change, and it is one plank length long.

Virtual Particle leap when Neutrinos change flavors

The neutrinos that do not change flavor travel AT the speed of light. The neutrinos that CHANGE flavor leap ahead by a Plank Length because during the change of flavor there is a Virtual Particle change that lets the new flavor leave the change area at the same time the old flavor reaches the change area. http://en.wikipedia.org/wiki/Virtual_particle
