Amptek Inc. introduces the first low cost Peltier cooled Silicon Drift

hi... i know what happens if electron runs into positron.
But what would happen, if a anti-proton runs into neutron, for
example?
would quarks annihilate with anti-quarks leaving behind a particle

Ok thank you all that have replied to my post. Frankly I am reall
interested in the theory of space travel in the near future. Th
problems which you all have said I already knew, I'm trying to fin
solutions to such problems. For intance the problem of re-entry t

"Corrections to Special Relativity"
    Special Relativity can be defined in terms of the Lorentz
Transformation. In a Force-Length-Time system of units, which are as valid
as the conventional Mass-Length-time system in common use, these

dr bhavasar and I were discussing that first make the particles go
backwards (use gravity I said) and then forward and they will go
faster than the speed of light.

HI All.  I am developing a motor using super elastic nitinol wire and have
problems.
Picture at: http://www.pacificsites.com/~snyder/motor.jpg  The most
frustrating problem is joining the wire together.  I bought some tiny

Thanks to an un-named poster (don't want to get him in trouble)
The way to do such is kinda simple in thought but of course
hard in the reality of the way you need to hold particles.

The aim to develop contact field optical microscope is: To study the
relationship between microscopic photon energy flow, and the material

In most global climate models, an increase in CO2 causes an initial
warming.  This initial warming leads to enhanced evaporation at the
surface and a general moistening of the atmosphere.  The added
moisture causes further warming due to water vapor being a strong

The fine structure constant alpha is said to be running
with energy as (from various QED textbooks)
1/alpha(E) = 1/alpha - (1/3 pi) ln (E^2/m^2)
where m is the electron mass, ln the natural logarithm,

If a 1 centimeter sphere that floats in water
half way normally just sitting there and has a mass of 1gram,
were dropped from 2 centimeters above the water...
What would the wave length from the first peak to the second peak be,
