Talk:2780: Physical Quantities

Planck Length here actually refers to the length of Planck himself. The same may apply to other names. 2659: Unreliable Connection (talk) 03:02, 25 May 2023 (UTC)

And here I was thinking it meant the length of Planck planking. Thisfox (talk) 22:00, 25 May 2023 (UTC)

I wonder if this is alluding to the Smoot, a unit of measure devised by MIT students to represent the height of Oliver R. Smoot. Probably worth a mention in the description nonetheless. Trimeta (talk) 03:45, 25 May 2023 (UTC)

Hawking radiation: ~100 W (through heat)

Planking is a thing.https://en.m.wikipedia.org/wiki/Planking_(fad) One pretends that one is a board, or plank. Are some funny pics. The opposite of planking would be good god how? How can even a cat!?!! [Special:Contributions/172.69.58.161|172.69.58.161]] 06:26, 25 May 2023 (UTC)

Hubble length is 13.2 m. 141.101.98.64 10:30, 25 May 2023 (UTC)

The m³ unit for Broca's area is surely a typo, right? 162.158.94.47 14:55, 25 May 2023 (UTC)

That would be my guess. I sent a note to Randall to ask. BunsenH (talk) 21:24, 25 May 2023 (UTC)

Just a couple of others: 1 Watt is what it takes to invent the condensing steam engine and Euler's number doesn't exist, because he died before telephones were invented. 172.69.247.45 15:08, 25 May 2023 (UTC)

There are lots of <someone>'s Number constants. We could have an entire phonebook of these. Barmar (talk) 17:53, 25 May 2023 (UTC)

I tried phoning Graham's Number, once. I'm still not yet finished dialling! 172.70.91.186 19:22, 25 May 2023 (UTC)

I thought you meant Alexander Graham Bell's number. 172.69.22.129 23:04, 25 May 2023 (UTC)

Shouldn't AG Bell's number be 1? Barmar (talk) 16:03, 27 May 2023 (UTC)

Chandresekhar's Limit = 3 pints? Barmar (talk) 17:53, 25 May 2023 (UTC)

Don't forget that numbers are now Euler letters! 172.70.85.137 20:41, 25 May 2023 (UTC)

From a friend, regarding Fermi's current temperature: The typical ground temperature of a burial plot in Chicago depends on the depth and the season. According to the Illinois State Climatologist Office, the average soil temperature at 4 inches depth ranges from about 25°F in January to about 75°F in July. The average soil temperature at 8 inches depth ranges from about 30°F in January to about 77°F in July. These measurements are made under grass, so the soil temperature under other ground covers or under bare ground may vary somewhat from those shown here. In the winter, when the ground is frozen, cemeteries are able to continue burying the dead by using special equipment such as frost rippers or steamers to break through the frozen layer of soil. They also use heaters or blankets to keep the graves open until the burial service is completed. RandalSchwartz (talk) 23:09, 25 May 2023 (UTC)

Assuming his grave is 6 feet deep and his body is at 5 feet deep, he's going to be below the frost line, which is 40" in Chicago, so the temperature is never going to drop below 32°F. Based on the charts at https://www.builditsolar.com/Projects/Cooling/EarthTemperatures.htm, he should see temperatures ranging from 40° to 62°. Interestingly enough, at that depth, the soil temperature will lag behind the surface temperature enough that the coldest temperatures will be in March and the warmest will be in September. 162.158.63.89 03:36, 26 May 2023 (UTC)

Pretty sure the Schwarzschild radius is the radius of a curled up child, not of Mr. Schwarzschild. 162.158.203.40 08:49, 26 May 2023 (UTC)

68cm diameter of a person curled up seems about right. 172.68.139.32 15:23, 26 May 2023 (UTC)

Besides Smoot, there's Erdős number.

The Erdős number (Hungarian: [ˈɛrdøːʃ]) describes the "collaborative distance" between mathematician Paul Erdős and another person, as measured by authorship of mathematical papers.

The Erdős number or Paul Erdős is 0. Anyone who collaborated with him has Erdős number 1, and anyone who collaborated with someone with Erdős number 1 (but not Paul Erdős himself) has Erdős number 2 - and so on. Taking this comic's interpretation, the Erdős number should be either 1, 'cause there was only one Paul Erdős, or 0, because he's dead. 172.68.139.32 15:23, 26 May 2023 (UTC)
