Reply to TIL Arabic numbers have only existed in their present form since about the 10th century. Only a few texts using Arabic numerals appeared outside of Italy until the late 15th century. It wasn't until the mid-16th century that Arabic numbers were in common use in most of Europe by joecooool418
Here's a fascinating video about Arabic numerals, and the Islamic golden age. For 4 centuries, the area now defined as Iraq and Iran was the center of intellectual wisdom. Then, a religious leader declared that numbers were the work of the devil - and that era died, never to return.

Reply to What type of converter piece would I need if I need a 1 1/2" PVC pipe to connect to a 2 1/2"vacuum hose? by longbdingaccount01
Keep in mind that 1-1/2 PVC has an ID (inside diameter) of slightly greater than that dimension (it's ID is 1.59"), and OD (outside diameter) of 1.90".
Vacuum hose diameters vary quite a bit. Your best bet is to go to your local hardware and try different PVC couplings with a sample of your PVC and vacuum hose. You might have to use 2 couplings.

Or, if you have an account in a local bank, go there. Most likely, a teller or manager can notarize you documents for free.

Reply to TIL In the history of the Catholic Church there has been over a decade without a Pope on the throne. The longest continuous time the throne was empty was two years ten months from 1268 to 1271. by jamescookenotthatone
Throne. This is one of the main reasons religion is illegitimate. Can you imagine Jesus wanting to be on a throne?

Reply to comment by Swanson11isaque in what do you think chance of life out of earth exists? by n-o-b-i-t-a
> 1000000000000000000000000000000000000000
That number (10^39) is about a hundred million billion too high - give or take a factor of 100.
Still, a reasonable estimate of stars (and, given an average of one planet per star, about the same number of planets) is about 10^22. It is almost inconceivable that earth is the only place with life.
Also, the first life could not have formed immediately after the Big Bang, because the only elements then were hydrogen and helium. These two formed the first stars, and after a few hundred million years, the larger ones could have exploded, forging the other elements that are necessary for life.

Reply to TIL In Approximately 241,000 years, Nanga Parbat #9 tallest mountain in the world located in Pakistan will overtake Everest and will become the tallest mountain in the world. by AdClemson
The concept of "tallest mountain" is based on sea level - which itself is not consistent. Due to Earth's rotation, sea level is farther from the Earth's center at the equator than at the poles. As a result, there is a mountain in South America (Mount Chimborazo's) whose peak is farther from the Earth's center, but because it is near the equator, it is not as high above sea level as Everest.

Unfortunate choice of adjectives. There are actually many sources of periodic bursts in the universe. "heartbeat-like" implies it originates from a sentient source.
