Not to diminish the bomb effort but at least they knew E=mc^2 three
decades before they started.
Now with peak oil everyone wants really fundamental research done "on
the wing."

Ok, hopefully this doesn’t just sound crazy, but I was just thinking
about a number of idea’s that look like they could work together.
Imagine, a large parabolic mirror, placed on the equator, and then try
to imagine a regular sized satellite, as a mirror in geostationary

What if you replaced the Leyden jars with large, modern capacitors?
Would that create a more powerful spark or what?

I keep seeing the variations of this puzzle.  Lately, a simpler versio
has cropped up.  Maybe it is too simple, or maybe there is no answer.
Let me rephrase:
Twins 1 and 2 leave two planets and travel at constant velocity toward

"Another Rebuff to General Relativity By Cosmological Observations"
    Cosmological observations have recently indicated that the "expansion"
of the universe to be faster at extreme distances than it is over most of
its observable volume. There have been attempts to reconcile ...

Why would laser diode arrays work better than laser chains like SHIVA
for laser propulsion?

 I'd like to ask this question: if I have heavy star in thermal
equillibrium with surrounding universe (e.g. it is in large cavity
with temperature T). Will the star radiate Planck's spectrum, or will
the Planck's spectrum be red-shifted by its gravitation? (Because

Which gives the most natural units ?
A)  epsilon0 = 1
or
B)  k=1/(4.PI.epsilon0)=1

I need some help in locating ceramic disc magnets that measure 120mm in
diameter with no hole in the center.  The thickness can be as much as 13 mm
25.4mm.
The strrength is not as important as the dimensions and that it be a solid

What you will need are these items...
gold fish bowl (large)
duct tape (2 rolls)
dry suit (the kind skin divers wear)

Hello this is Conrad Countess. I first published this idea of c^2 as a
frequency at the high end of the electromagnetic spectrum where energy
turns to matter back in May of 2005 on sci physics and got some
interesting responses. I explained it as the speed of light in linear

I'm trying to understand how RFID tags work.  One large class of tags
is "inductively coupled," which I understand to mean that an
alternating current applied to a coil in the reader tends to induce a
current in the coil of the tag.  The circuitry in the tag can change

can you recommend me useful links about informations on how to
calculate heat of coal fired boiler. Boiler is with natural
circulation with drum. It has 6 coal mills. I wonder if possible to
calculate input heat to a boiler, and what variables I need?
