The history of light if funny.

First people thought it was a particle, as per corpuscular theory of light, notably Newton supported the corpuscular theory of light.

But then evidence of the diffraction of light start to become unbearably strong, culminating in the Arago spot.

And finally it was understood from Maxwell's equations that light is a form of electromagnetic radiation, as its speed was perfectly predicted by the theory.

But then evidence of particle nature started to surface once again with the photoelectric effect. Physicists must have been driven mad by all these changes.

Near field approximation to Kirchhoff's diffraction formula, i.e. when the plane of observation is near the object diffracting.

This is one of the the key innovations of the Illumina (originally Solexa) sequencing.

This step is genius because sequencing is basically a signal-to-noise problem, as you are trying to observe individual tiny nucleotides mixed with billions of other tiny nucleotides.

With bridge amplification, we group some of the nucleotides together, and multiply the signal millions of times for that part of the DNA.

Kind of a synonym for hydrogen emission spectrum not very clear if fine structure is considered by this term or not.

A line set for hydrogen spectral line.

Formula discovered in 1885, was it the first set to have an empirical formula?

A gene that got duplicated withing the same species. The copies may diverge in function from the original.

Important example: hox genes.

First Amazon hire, wrote and led the team that wrote v1.

He looks like an older and more experienced dude compared to Bezos at the time.

. www.geekwire.com/2011/meet-shel-kaphan-amazoncom-employee-1/2/ also mentions that unlike California, there's no sales tax in the state of Washington, which is important for selling books.

TODO where can all videos be found??

www.aip.org/history-programs/niels-bohr-library/ex-libris-universum/harvard-project-physics-role-history-science mentions that they have a special focus to the history of physics, as can be seen e.g. on The World Of Enrico Fermi by Harvard Project Physics (1970).

Google has put considerable effort into custom hardware to greatly optimize its stack, in a way that is quite notable compared to other tech companies.

Basically it looks like the dude got enough money after selling some companies, and now he's doing cooler stuff without much need of money. Not bad.
