Some research might be needed to see what things “Quantum Annealing” might apply to.

  • AI
  • Electronics (transistors, Fets, Mosfets and so on)
  • Particle physics and strangelets
  • There should be around 200,000 civilizations in our galaxy that are able to visit the earth now:, but so far we have found none, despite increasing evidence that earth like planets exist in our galaxy. This may be because of a unforeseen danger that all advanced civilizations might face—that essentially destroys them. If such a danger exists, then the question is: are we near and event that will destroy humanity. Certainly the strangelet thing above is one example of what could go wrong, but there are probably lots of other things also. For example each one of us now holds increasing amounts of energy at our disposal as our civilization advances—does that mean that each one of us now holds a greater responsibility in ensuring the human races survival in the future?” Why have we not discovered a advanced civilization on another star, or why has not a advanced civilization not contacted us yet? Perhaps this minimum energy physics/mathematics could be reapplied to other fields like determining why life should, or should not exist in our galaxy.

In maths, there is also (a feeling for the author right now) that maths can be translated to other problems because of its abstract nature. The author likes that saying by Einstein “if I knew what I was doing, it wouldn’t be called research.” That feeling of using math’s ideas for various things comes from engineering modeling[1] and by playing around with the equations that calculate the momentum imparted by a photon striking a solar sail—the author understands it when some of you wonder how a astronaut might be propelled in space by using a flash light, or how a spacecraft with a solar sail might move.

The author has not currently got the time to research connections between this and strangelets: “If the strange matter hypothesis is correct and its surface tension is larger than the aforementioned critical value, then a larger strangelet would be more stable than a smaller one. One speculation that has resulted from the idea is that a strangelet coming into contact with a lump of ordinary matter could convert the ordinary matter to strange matter.” source:

The current thoughts on this with respect to the particle accelerator is that if something like that can happen, then it would have already have happened here or some place else in our galaxy, since high energy cosmic rays strike the atmosphere or the surface of planets, moons, or asteroids without atmospheres. No strangelet matter has been found by scientists and astronomers so far. Meaning that it is unlikely that such a event would occur—however the author’s research did show that strange particles were produced as part of the process of finding the Higgs boson (but not necessarily strangelets).

Big Questions: The Ultimate Building Blocks of Matter

String theory is included in this, and that leads to other fascinating topics, such as gravitons traveling between banes.

1. “Air is not always the best test medium to study small-scale aerodynamic principles, due to the speed of the air flow and airfoil movement. A study of fruit fly wings designed to understand how the wings produce lift was performed using a large tank of mineral oil and wings 100 times larger than actual size, in order to slow down the wing beats and make the vortices generated by the insect wings easier to see and understand.” Ref:
