Academic grants can work in a lot of ways. It is common for a significant chunk to be taken as overhead by the university (20-40%). This is generally smaller for senior members of the faculty who bring in more grants. The PI (primary investigator, read: dude with a reputation) tends to get 5-10% to run the program, and then another 30-40% goes to salaries for researchers working under them (read: grad students). The rest, on the order of 20%, goes to capital costs like materials, time on expensive machines, or prototypes.
So this guy probably got paid $1-2M directly for the grants over maybe 3-5 years. Note I haven't looked into his specific situation.
For #3, I'll tell you how I learned to meditate.
Start with short sessions, maybe 10-15 minutes. If you prefer, start with an audio guide. Try to focus on the process and remove any other ingredients. Count breaths, find a comfortable sitting pose, and work through any intrusive thoughts until you have a clean slate. If you can get through to a point where the sounds, smells, and light around you doesn't pull you out of this "empty" state, you'll find a clearer, more balanced mental state waiting for you on the other side of the session.
Electric motors actually work on a number of principles. Depending on the magnetic topology these can include multiple factors or just one.
The classic DC motor is just a mechanical commutator (rotating switch) that alternates the polarity of pairs of electromagnets, causing pushing and pulling on the rotor to occur at appropriate times.
AC motors are generally based on multiple electromagnets acting in unison to produce a rotating field. This is then used to twist a magnetic rotor (just like how a compass works).
Other styles like the modern brushless motor are dependent on sensors (or equivalent devices and algorithms) to achieve the same effect as the DC motor above. The difference is that you can have more pairs of magnets (poles, pole pairs) so you can produce smooth torque by phasing at least three groups of poles that hand off to each other.
Advanced topologies like reluctance motors use the same principle as a fridge magnet, leveraging the attraction of an electromagnet to a chunk of steel on the rotor. Again, phasing is used to smooth out the interaction.
For more details, look up the principles of magnetic reluctance, induction (and Lorentz force), and Maxwell's stress tensor.
Really excellent article with just the right amount of bizarre and nostalgic content.
Depending on your situation there are some doula services that are partially or fully covered by some medical groups. Varies state by state and depending on income and other factors, but can be a few visits or so. If you talk to a doula collective they may have more info for your specific area.
Totally hear you. First few weeks are tough. Some kids are harder than others, and you're learning a lot too. Good news is that they get easier, and you will get better at it. Also, a couple months in they start smiling and you get some encouragement finally.
Until then - consider a postpartum doula and a housecleaner. Takes money, but your life and family are worth it if you are able. You can't get all the independence back, but you can get enough.
This thread has some great ones, and quite a few of the folks I'd consider the best. But I haven't seen anyone mention Stuff Made Here! What gives?
I highly recommend Hype Machine for properly new and sometimes unexpected music. Downside is that you need to sort through some stuff you might not enjoy but upside is pretty solid when you find a new artist! More organic than any of the prediction-based discovery apps.
