    D cell battery gets hot

    Its the battery sometimes Hi, I had it happen last week (24 July 2013) to a Duracell D cell in a flashlight. One battery dated 2005 that was still good had gotten hot inside the flashlight. I had trouble with the switch and left it on the kitchen table. An hour later I touched it and wow...

    Axial rotation of a magnetic field detection

    The question Im asking is not the obvious question. Yes I know that time variant magnetic flux induces a current in a loop of wire or a moving wire cutting lines generates a current......My question, again, is "can I detect a spinning magnet that spins on its magnetic axis"? There were rumors...

    Gravity hysteresis.

    Gravity waves of star pairs carry away energy A book by this great Physicist does have much that has been discussed in this topic. John Archibald Wheeler, "A Journy into Gravity and Spacetime", 1990 (rep 99) 257p, soft, 8x9 blu cover. A loan from a friend who got it Jan04 at Barnes and...

    Axial rotation of a magnetic field detection

    Clarification of my question I should clarify my question. I can detect a magnet presence with a wire cutting the lines, yes, but can I detect a spinning magnet that spins with the axis if its flux the same as the spin axis? And then, is a spinning electrically generated magnetic field any...

    Axial rotation of a magnetic field detection

    Since the archive didnt have an answer or these keywords, is there any way to detect a magnet spinning on its axis so the magnetic field is rotating axially and lines of flux are rotating around but nowhere in space is the flux level changing? Ive heard rummors over the years. This is not the...

    Any questions?

    Question for Mars team Was this mission kinda nervewracking due to the current solar maximum and the not knowing if a big solar flair would come up during the flight? Were the computers and memories sheilded for a worst case solar wind? It seems more optimal to go to mars 5 years from now at...

    Gravity hysteresis.

    Thanks for the replies to my questions. Stingray, very interesting but only makes me want more details. Orientation to wave? Observables compared to accelerationg interferometers? Where to get example calculations of gravity wave experimental setups? Ranyart needs to cite references. Ive...

    Looking for a good book

    Here is one My copy looks promising. Its called Fundimentals of Astrodynamics by Roger R. Bate Donald D Mueller and Jerryr E White, 1971, 454 pages,14$, and continuously in reprint at Dover Publications Inc. I have their hard copy winter 2004 catalog of Math and Science. You can order online at...

    Gravity hysteresis.

    Thanks for math.ucr.edu link Im begining to understand my gravity questions. The link http://math.ucr.edu/home/baez/physics/index.html says that gravity outside a black hole is the ancient field at the moment of black hole creation and is frozen just as the electric charge is frozen. The...

    Help on Leidenfrost effect

    Is this the definition? LEIDENFROST EFFECT - Where a liquid will not wet a surface and becomes insulated from the surface by a layer of vapor if the surface is above a critical temperature of the liquid. The surface is usually well above the liquids boiling point. Water beads seems to last...

    Doppler & Absorption

    What you see is what you get The light after the absorbing coud is the light you have to see and experiment with. If the sodium line is now visible (cloud or no cloud inbetween) due to doppler shift it cannot be used in your (what ever) experiment. This is the Radial Doppler Effect. Can we...

    Gravity hysteresis.

    Further gravity questions Ive read nearly every super string and cosmology book. Ive formed some basic questions that gnaw at me while reading. Ive tried other physicists and they ignore my mail. Its simple basic stuff that is not given a chapter in any book. Laymen like me need grounding...
