How Do You Tell Time (Period) in the Universe Video?

Have you got a off who's there for you 24/7? And not presently some days, 365 days a year? You have to think you're attractive special, right? Well, Michael from Vsauce has got a number of sick burns for you, since if your buddy truly has your back, 24/7/365 just isn't high-quality enough. On this big blue marble we call Earth, 'all the time' equals 24.0000006/7/365.2421891.

That ludicrous nerd burn is actually the basis of some pretty strange historic anomalies. Like, did you be acquainted with that George Washington had 3 birthdays? If you Google it, you'll get 22 February 1732 for George Washington's birthday, but if you go correct to the source of his family Bible, you'll see it written as "11 February 1731/2". So which is it, George? What are you beating back there?
Not just that, but in 1752, the UK seems to have lost 11 entire days in September. Check out a calendar - they're just not there.
There's a high-quality reason for all of this weirdness, and it comes down to how Earth moves in relative to the rest of the Universe. Yep, we're chatting about the concept of time.
We all recognize that Earth spins on an angle as it spins around the Sun, but that extremely motion means that no one point on Earth is experience time in the same way.
While strictly your meridian - the line between the north and south poles that you're at present standing on - determines the precise time of day it is, we've had to generalise into much easier, but far less precise, time zones (for obvious reasons).
Figuring out these universal and limited time zones according to what a day, month, year, and still hour it is was no small feat for humankind to wrap its head around, since what are these hours and days deliberate in relation to? How do you measure something in family member to the entire Universe?
Check out the episode of Vsauce underneath to find out, and gain a whole latest perspective on presently how very awesome it is that we still have calendars and watches, and GPS devices with clocks that get Earth's gravitational pull into thought. Thank you, science.
