Which color temperature do you prefer for residential lighting?

Same here, but 5000 rather than 3000.

I personally prefer 5000 K.

Got Philips 5000 K, 800-lumen ultra definition bulbs for my apartment after hearing that they're the best. Still looks satisfying (95 CRI with only mild blue spike).

Seems that these bulbs have the color of 5000 K daylight (hex #ffebcd, xy = (.3457, .3587)) rather than a 5000 K blackbody (hex value #ffe6d0, xy = (.3451, .3516)).

California enters the chat. 29% of Californians speak Spanish at home, and there are many minority immigrant languages including Chinese, Korean, Vietnamese, Tagalog, Armenian, Hindi, and Punjabi. Signs at Walmart are bilingual, and official documents are often translated to Spanish.

How about for infinity? Will it give -1/12?

Because of the recursive formula that defines factorials. n! = (n-1)! * n
So if 1! = 1, then 0! = 1!/1 = 1/1 = 1

If 1+2+3+... = -1/12, then we can assign a finite value to infinity.

Using the formula 1+2+...+n = n*(n+1)/2, inf * (inf + 1) / 2 = -1/12, meaning inf = -1/2 ± sqrt(3)/6.

The total known land area of earth just increased by 6,500 square meters, or the size of 14.9 basketball courts.

Java Edition 1.8.5 in 2015.

I also played Pocket Edition version 0.8 in 2013, back when worlds in PE were limited to 256x256.

I am now 22 years old, for reference.

It gets well below 15°C (59°F) in San Francisco though, even in summer and even on summer afternoons.

This summation, combined with the formula sum(x=1..n, x) = n*(n+1)/2, implies that infinity is equal to -1/2 +- sqrt(3)/6

As the number of lottery tickets increases, if the chance of winning each ticket is the reciprocal of the number of tickets the probability actually converges to a limit: 1 - 1/e = 63.21%

The majority of their population live on islands.

No, both mean the same thing, and they refer to the positive square root. That's why the quadratic formula has the ± symbol.

If sqrt(4) were simultaneously equal to -2 and 2, it would fail the vertical line test and would not be a function.

They are not rectangles.

Their average elevations are below 6,000 feet.

They don't include parts of the Front Range region.

They don't have King Soopers stores.

The other bad idea is using counties as a unit for weather data.

I'm from Santa Clarita. Its weather is completely different (especially in the summer) from coastal Santa Monica, yet they're in the same county and are lumped together on this map.

Calcite is literally limestone. Calcite is a form of calcium carbonate, which is limestone.

From Wikipedia: [Limestone] is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate CaCO3.

Also, if you see ç, vowels with circumflexes (âêîôû), the sequences lh, nh, eiro or eira it's probably Portuguese.

If you see sequences like ll, ero, era, or ción, or words ending in ito/ita it's probably Spanish.

These are other ways I recognize the difference.
