In order to introduce a tensor description of motion we will consider in our space-time the “world line”, i.e. a line that describes the history of a moving point and we will parametrize this line with the aid of the line invariant interval element ds=dxidxi=cdτ where dτ is the particle’s proper time such that dτ=dt1-β2 and as before β2=1c2dx2+dy2+dz2dt2=v⃗2c2. We can then build another 4-vector, the unit tangent to this trajectory line, with dimensionless contravariant components ui=dxids:(11-β2,v⃗c1-β2) and this is the only 4-vector that can be formed based on the classical velocity 3-vector v⃗. We therefore see, after introducing the scalar mass m, that pi=mcdxids=mdxidτ:m(c1-β2,v⃗1-β2)=(Ec,mv⃗1-β2) where E=mc21-β2≃mc2+12mv⃗2=mc2+T=mc2+kineticenergy is a 4-vector.
Chess vs Chemistry

what does a physicist has to do with chemistry?
It was about chess members anyway!
I don't get the joke and I really want to. Help me, please.
Oh, 2900, 2500, 2700, and 2500 degrees Farenheit? I get it now! And spectra!
Please try to sort this puzzle with help of the Periodic System of the Elements if needed.
I put 1 equal meassure of Iodine and Zinc Oxide in an Erlenmeyer Flask and I heated it up to 2900 Fahrenheit.
I Put 1 equal measure of Boron, Uranium, Xenon and Oxigine in another Erlenmeyer Flask and I heated it up to 2500 Fahrenheit.
Iodine Zinc Oxide is highly unstable and quickly falls apart, the other alloy gets highly active and absorbs to energy that the unstable ally had lost and pushes its temperature to an incredible 2700 unFairenheit, the unstable ally now drops to 2500 Fake&hide.
Ran both mixes of metal/non-metal matter through a computer program to find their true compositions and there is almost now difference in their spectra. Therefore could we say.
I Z O = B U X O ??
Please help out because my report should be handed in soon at the Laboratory.
Thanx
