This is fun! but not so surprising to me: 987,654,321 + 123,456,789 = 1,111,111,110 1,111,111,110 + 123,456,789 = 1,234,567,899 \approx 1,234,567,890 So 987,654,321 + 2 x 123,456,7…

There is Smartsheet, which mostly works well for this, but its power-user features are pretty limited compared to Excel.

Are you sure? I recall that the dish was spherical, not parabolic, and had a movable receiver mounted on cables; moving the receiver adjusts the direction from which signals can be…

Sorry, that should say “coherence length”.

No defects needed for flux penetration in a type-II superconductor. When the conference length is smaller than the penetration depth (up to a factor of sqrt(2)), flux vortices can …

Yes, black holes are theorized to evaporate due to Hawking radiation [0]. [0] https://en.wikipedia.org/wiki/Hawking_radiation

There is a nice calculator for terminal velocity of a sphere in air here: http://hyperphysics.phy-astr.gsu.edu/hbase/airfri2.html That being said, I'm not sure how relevant termina…

This sounds like a kind of historical GeoGuessr.

I think OP means “disconnected past” as the spacelike-separated region south of the “now” slice. Boosting could transform points in this region into the spacelike-like separated re…

Regarding the turn signals - do you use a right-hand-drive car? Is the turn signal stalk on the right side? OP's description is consistent with my left-hand-drive experience, with …

You are off by a factor of ten [0]. [0] https://home.cern/resources/faqs/facts-and-figures-about-lhc

I think this is the difference between two kinds of "wanting", the id kind and the superego kind. We want the chips because they taste good. We want the nutritious food because we …

I suspect much of the Morse that you hear is radio amateurs (hams) talking to each other. Morse, being a very narrow bandwidth signal, is hardy against noise and low power situatio…

Are there really any microwave ovens that use klystrons? I thought most if not all commercial microwave ovens used magnetrons.

For those interested in growing tropical & sub-tropical plants from seed - mangoes, avocados, citrus, papayas, etc. - Melvin Wei [0] has a great youtube channel. There is a certain…

I have had a good experience with the browser plugin floccus, which I use to sync bookmarks to a self-hosted NextCloud instance. It has cross browser support. I have a 'sync' folde…

1 meter is about 27 orders of magnitude down from 100 Gly, and 12 up from 1 pm (approximately the proton radius). So we are closer to the small side.

For some time now, for buying home improvement tools, I have followed the heuristic “buy the cheap one, then once it breaks, buy the expensive high-quality one.” I find that this h…

I think the "track count" has to do with the number of tracks available for mixing in the sound editing stage, not how many channels are in the final mix. At the time the sound edi…

I would expand on this to say that they propose to use an innovative cavity shape. Normal-conducting cavities can reach higher accelerating fields than superconducting cavities, bu…

> If property values in my neighborhood go up will I be forced to sell or refinance my house to pay the tax bill? Pardon my ignorance, but isn’t that how it works (outside of Calif…

As an accelerator physicist - while some earlier machines were built without vacuum beamlines, nearly all modern[0] accelerators are built with ultra-high vacuum beamlines. Beam qu…

I'm in a very similar boat. My best solution so far has been to use Onenote and Outlook plus paper, but I'm looking for something better. Maybe org-mode or a personal wiki? In Outl…

They're not totally separate concepts though, no? The definite integral is the difference of two values of the indefinite integral (antiderivative). I suppose if you're talking abo…
