WARNING: WORK IN PROGRESS

The true sciences are physics and chemistry. (Physics explains all of chemistry.) Physics has many problems that go back to early in the 20th century. This is about physics problems physicists don’t/won’t talk about and usually refuse to admit as problems.

**Quantum Field Theory.** This is the theory that drives all of physics except General Relativity (gravity). So what is a field? Standard answer: “You have to know a lot of graduate-level mathematics and even then …” Interpretation: no one has a clue. But it all sounds good. Sort of like asking about consciousness.

**Size of an electron.** This gets complicated fast.

Answer #1: “For the **Electron**, the mass and charge is known – that’s all. **Electrons** exist as point charges with no **size**.”

Answer #2: “Electrons in quantum mechanics have a wavefunction, as do all quantum objects. This describes the probability distribution of the electron: how likely you are to find it in a particular place with a particular momentum and spin and so on. Critically, quantum mechanics means that the wavefunction isn’t just a description of our lack of knowledge: nothing in the Universe “knows” where the electron is “inside” the wavefunction before one looks for it.” And so on …

Answer #3: “The electron size can be described in three different ways: 1) how its size compares to the proton radius; 2) how its size collates to its classical radius; and 3) how its size relates to the hydrogen atom’s ground radius.

1) 2.103 x 10^-16m or proton radius) / 137.036 = 1.5346 x 10^-18m or size of electron.

2) 2.8179 x 10^-15m or electron classical radius) / 1836.152 = 1.5346 x 10^-18m or size of electron.

3) 2 x (1.321 x 10^-15m or proton Compton wavelength) x (5.2917 x 10^-11m or H-atom ground radius) / 9.1103 x 10^-8m or wavelength of photon with -13.6 eV of energy that is related to the H-atom’s ground state) = 1.5346 x 10^-18m or size of electron.”

Give up?

**Electron-positron high energy colliders.** Electron and positrons are point particles. Everyone says so. So how do you collide a point with a point? There are an infinite number of points between two points so no matter how narrow you make a beam of point particles there are still an infinite number of paths. So what is the probability of two paths out of an infinite number coming together? Even with the electron having a wave function in two directions, it is still two out of infinity. Think about it.

**Synchrotron Radiation.** Synchrotron radiation (also known as magnetobremsstrahlung radiation) is the electromagnetic radiation emitted when charged particles are accelerated radially, e.g., when they are subject to an acceleration perpendicular to their velocity (a ⊥ v). This is why the LHC is underground and no one is in the tunnel when it runs. There is no fully understood theory for this radiation.

**Hawking Radiation.** Stephen Hawking was a highly regarded theoretical physicist but nothing he ever produced was ever proven. He was famous for traveling with an entourage.

**The Twin Paradox.**

**Double Slit Experiment.**
