Three cheers for the black death

✤Kicked off the industrial revolution

✤Built up resistance to AIDS

✤Gave Newton time to discover gravity

The Apple & the Moon

Why should that apple always descend perpendicularly to the ground…Assuredly the reason is, that the Earth draws it. There must be a drawing power in matter. And the sum of the drawing power in the matter of the Earth must be in the Earth's centre…Therefore the apple draws the Earth, as well as the Earth draws the apple.

Although he had been undistinguished as a Cambridge student, Newton's private studies at his home in Woolsthorpe [1665-1666] saw the development of his theories on calculus, optics and the law of gravitation

Thermodynamics & gravity

•Surface gravity ~ Temperature

•Area ~ entropy

•Mass ~ energy

Verlinde’s entropic gravity

For me gravity doesn’t exist,” — Verlinde

Mass, energy, & momentum

•Tardyons - slower than light, massive

•Photons - Are light, no mass

•Tachyons - faster than light, imaginary mass

superluminal neutrinos?

Baseline of 730 kilometers, arrival too early by 60 nanoseconds: speed of neutrinos is 2.48

10-5 c too fast

A disputation Of Ideas•Forbidden by cherenkov radiation

•Ruled out by SN1987A

•Clock comparison wrong

•Group velocity is not info velocity

•Short cut via another dimension

•Neutrino speed is really the limit

•Clear evidence for pet theory x

Non-barking Higgs

If a Higgs particle is produced in a proton-proton collision, an LHC detector might infer what you see here. The four straight red lines indicate very high-energy particles (muons) that are the remnants of the disintegrating Higgs.

How will it fall out?

•Emergent gravity

•Frame dragging

•Superluminal neutrinos

•Nobel for discovery of accelerated expansion of universe

•Higgs has fewer & fewer places to hide
