In summary: Today I learned that Lagrange was Italian and that he lamented the execution of Lavoisier in France during the French Revolution with the quote:"It took them only an instant to cut off this head and a hundred years might not suffice to reproduce it's...brains."

No, single profile, with multiple personalities.

Just to quash the scurrilous rumors that have been circulating in certain quarters, I too deny that I am a clone of myself...
The question is, what does Mark43 have to say about it?

And initial water temperature 20.435°C or 20.44°C ? These are the big issues that need to be categorized! How else one can sleep at night?

Wouldn't stop drop and sink summarily extinguish the flames?

Today I learned the widely used "10 other cells per human cell in a human body" is probably wrong. A 2016 study revisited the estimates with improved methods and its result is 1:1.

(It was always clear that most of the mass of a human body is in human cells - that is easier to measure. The human cells tend to have much more mass per cell than foreign cells).
 
  • #2,650
So a Bacteria masses 1/350 what a Human cell does. That is quite a dynamic range. All that extra DNA maybe?
I wonder how a Virus compares, maybe a common cold virus.

TIL that there is such a thing as "... standardised to the European Standard Population". Quite logical if you think about it, but I never had thought about it.

TIL about personal responsibility. It's not fun cramming for school projects when the end of the semester is in a month and a half. Now I'm doing stress-relief math at 2 am.

Today I learned that "Bohemian rhapsody" is the most performed song of the 20th century. Perhaps I should change the title of my recent paper linked in my signature and call it "Bohmian rhapsody for instrumentalists".

TIL about the following site:
This link will display the photo for the current day. With your cursor on the picture, the symbol ">" on the right shows you the previous day's photo. If you keep clicking on this symbol, you will see the series of photos day by day going back at least to December 2017. I do not know how far back the series goes.

Hope you find this entertaining, but beware, it can become addictive.

Today I learned about the airport cell phone lot.

For the first time in several years, I had to pick up a guest at the nearest airport. I figured I would do what I had done before, namely park in the garage, go into the terminal to meet him at the baggage claim, then pay a couple of dollars when leaving the garage.

Along the entrance road, I saw a sign, "Cell Phone Lot." Aha! I could park there for free, wait for my guest to text me his location at the curb in front of the terminal after he arrived and picked up his bags, and then simply zip over to the terminal. This is not a huge airport like Chicago O'Hare, so just 2-3 minutes after his text, we were on our way.

As I was leaving the cell phone lot, I noticed that most of the other cars were parked facing the opposite direction to me. Behind me (and in front of them) was an electronic flight arrival board similar to the ones inside the terminal. I hadn't noticed it when entering the lot, and I was checking the arrival status on the airport's website on my phone anyway, so I didn't really need it. It reminded me of a drive-in movie theater. :cool:

Just now I've read online that some cell phone lots also have restrooms, and even food trucks to provide refreshments.
