Time Travel Into the Future
There are two ways that one can legitimately travel into the future. Method 1 - Moving Objects Age Slower Thanks to Einstein's work on the nature of time, there is…
deBroglie Matter Waves–Some calculations utilizing the wavelike nature of matter
Probably the most startling revelation of Quantum Theory was the postulate that all particles have a waviness to them. Initially, when this was proposed for photons, physicist were more open…
What quantum entanglement is not
Quantum Entanglement and the Sock Pair I recently found a ‘highly upvoted’ answer on quora around the question – How exactly does entanglement work? How can a (measurement on a)…
Graph of Dirichlet Function
I often wondered what the graph of this weird function would look like…A function that equates to 1 for all rational x and equates to 0 for all irrational…

How does an alpha particle get out of the nucleus?
Alpha particles do not have enough energy to leave the nucleus of an ; Yet, they somehow are able to set themselves free. This is due to the uncertainty energy…
The Failure of Ether, Constancy of the speed of light
Light, it was already known, moved at a constant speed. If light was moving at a constant speed, it begged the question - constant relative to what? That something was…
Quantum Computer Calculations, Quantum Computing Executive Workshop
As discussed in our live quantum computing workshop, the result of a quantum computation is probabilistic. However, in certain cases, it is fully deterministic , as in the case of…
