Short for Doctor of Philosophy, it's how some weird places like the University of Oxford say PhD. In Oxford they also analogously say MPHil.
Whenever you make a change to your material, people should still be able to access the previous version.
Maybe there was something in the previous version that they needed, and you just removed.
Git + GitHub is the perfect way to do versioning.
How Humans Lost Their Fur by PBS Eons (2020)
Source. Says it is linked to bipedalism to help hunting in hot weather. But could only happen fully after the invention of fire, otherwise you'd be too cold at night.I had meant to make an update earlier, but I wanted to try and add some more "visible end-user changes" to OurBigBook.com.
Just noticed BTW that signup on the website is broken. Facepalm. Not that it matters much since it is not very useful in the current state, but still. Going to fix that soon. EDIT: nevermind, it wasn't broken, I just had JavaScript disabled on that website with an extension to test if pages are visible without JavaScript, and yes, they are perfectly visible, you can't tell the difference! But you can't login without JavaScript either!
I still haven't the user visible ones I wanted, but I've hit major milestones, and it feels like time for an update.
I have now finished all the OurBigBook CLI features that I wanted for 1.0, all of which will be automatically reused in ourbigbook.com.
The two big things since last email were the following:
A secondary but also important advance was: further improvements to the website's base technology.
I knew I was going to do them for several months now, and I knew they were going to hurt, and they did, but I did them.
These change caused two big bugs that I will solve next, one them infinite recursion in the database recursive query, but they shouldn't be too hard.
The China front was of course the Russia front this time: stackoverflow.com/users/895245 (web.archive.org/web/20220322230513/https://stackoverflow.com/users/895245/ciro-santilli-Путлер-Капут-六四事)
One cool thing we did in this procedure was to use magnetic separation with magnetic beads to further concentrate the DNA: Figure 1. "GE MagRack 6 pipetting.".
The beads are coated to stick to the DNA, which allows us to easily extract the DNA from the rest of the solution. This is cool, but bio people are borderline obsessed by those beads! Go figure!
Then we prepared the DNA for sequencing with the Oxford Nanopore specific part: Oxford Nanopore SQK-LSK109 Ligation Sequencing Kit.
Here some of the steps required a bit more of vortexing for mixing the reagents, and for this we used the VELP Scientifica WIZARD IR Infrared Vortex Mixer which appears to be quicker to use and not as strong as the Vortex Genie 2 previously used to break up the cells:
After all that was done, the DNA of the several 400 ml water bottles and hours of hard purification labour were contained in one single Eppendorf!
Classic theory predicts that the output frequency must be the same as the input one since the electromagnetic wave makes the electron vibrate with same frequency as itself, which then irradiates further waves.
But the output waves are longer because photons are discrete and energy is proportional to frequency:
The formula is exactly that of two relativistic billiard balls colliding.
Therefore this is evidence that photons exist and have momentum.
