(Recommended)Popular Videos : [Veritasium] How We're Redefining the kg

 

This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Playtime Comments : [Veritasium] How We're Redefining the kg

Fi****:

5:00 Yes, I can definitely see why they call it the "Watt", because that's what everyone says after you explain it to them.

Un****************:

0:21 I'm at least 50% french and I'm so proud. Good luck with the replica!

Al******:

/r/MapsWithoutNewZealand at 0:35

Or at least, without the North Island

lu*********:

1:40 aha! unchanging you say, but how have you defined the length of a second!?

Wa********:

8:33 My Physics class in the nutshell

Ma***********:

When you pass without studying... 8:35

Ni************:

8:42 Hey V-sauce, Michael here

Af********:

Who watches Veritasium even though they don't understand anything (I can't be the only one)

sa******:

It is awesome that there is a science channel that does not try to overly popularize a subject. For people with knowledge on physics this was extremely informative. I can now easily describe how the kilogram is defined. Thank you!

Da********:

hey!! you have made a lot of videos on kilogram. first from "the roundest object". You have put a lot of weight on the kilogram.

Fl**********:

so four potatoes about a kilo...init?

Br***************:

Please a video on definitions
Of all 7 si base units

Gu***********:

The next General Conference on Weights and Measures is so close now! November 13-16, 2018. We will be getting new definitions of the kilogram, ampere, kelvin, and mole (according to Wikipedia)!

Fl********:

When they locally mapped 'g' in the room's surface plane, it reminded me of Rick making an 'absolute level' surface from Morty's Mind Blowers.

Yu*************:

Watching this on May 20, 2019.
SI units have been officially redefined today, kg is defined by Planck’s constant.

Jo*****************:

R.I.P., Elder Kg, 1799-2017 You'll be missed.

LX**********:

Game of Life 1.15.2:
- Minor bug fixes.

Ke**********:

1mberto me trouxe aqui, kkkkkkkkkkkk

Cr***:

RIP my brain

Co**********:

The US has a Kg, now it is time to stop all the sillyness and to start using it.

R*:

I will have to come back and watch this video again when I am not high

Ar*********:

Physics Teacher : Mass is defined by physical quantity of platinum iridium alloy located at Paris
WAITING FOR THIS VIDEO
Me : No it is defined by Planck's constant.
(Finally)

Al*********************************:

Man, that's heavy.

Re*********:

opa, então você veio pelo Umberto??

Av******:

drugs dealers are going back to school because of this

Ne*******:

Ladies all over the world are going to freak out when they find out their scales are under-reading by 0.00000000000000001kg all along.

Ko**********:

My physics teacher literally recommended your channel to our class, guess who's watching your videos now? Edit: As a VWO6 student I should know how to speak English XD, dutch people will understand

Ta********:

One Balance to rule them all, one balance to define them.
One balance to standardise them all, and into light forever bind them.

Sm*************:

Another thing.. I thought the fact that you've locally mapped g in the room was FASCINATING.

Do************:

This episode was way better than most of the others.

MA*:

I like absorbing as much knowledge as i can from your vids bc even if i didn't get it all I'm at least a little less ignorant than i was 949 secs. Ago

Ro*********:

Hey Veritasium
I was part of the team working with Bryan Kibble on the NPL mkII Kibble Balance (aka Watt Balance, aka Moving Coil experiment) between 1991 and 2000. Firstly I'd like to congratulate you on a great video. It's not easy explaining this elegant but complex method of redefining the kg and you guys did a good job.

One thing to possibly add is the importance of keeping the magnetic field constant. Both weighing and velocity measurements are not quick and are conducted over a long time period. Back then it lasted over an hour, and the field strength is highly susceptible to temperature changes, so keeping the large magnet at a constant temperature is imperative. I worked on the NPL system and we managed to keep the temperature drift down to a millikelvin or two over the duration of measurement, usually overnight.

Om*****:

Its true now!

Ly**********:

At least they will now know Planck's constant to infinite decimal places

Sp****:

-It's that easy, yeah.
-It's that easy.
Me: Ok, I am out of here :D

RM***:

Every time he says “kilogram,” all I hear is “kill a gram.” Hey, I’m all in favour for weight loss…

Th***************:

Just imagine if the janitor erased that whiteboard

To****:

The kg is dead, long live the kg! All hail the kg!

Ma********:

R.I.P. the 1-kg mass in France. You'll be remembered.
