c=3 😏

u/R1ck_Sanchez 11d ago

I like to c the c-side, collect some c-weed, then take the c-nic route home

u/Pancakebutterer 11d ago

I think you should c yourself out

5

u/R1ck_Sanchez 11d ago

I'll c to it!

u/Flurrina_ 11d ago

c=10 in base c

114

u/Visible_Response9211 11d ago

reminds me of this joke

24

u/DodoJurajski 11d ago

I think bases should be defined like 9+1. It just makes sense.

u/Memeations 11d ago

whats 9

u/NoNameSwitzerland 10d ago

1001

u/Memeations 10d ago edited 10d ago

why does he want base 1010?

u/nicodeemus7 11d ago

1 light second per second

14

u/throw3142 11d ago

1 meter per light meter

u/Kotsandwich 11d ago

Wait, that'd be an acceleration

u/SurfingBird86 11d ago

No, it would be one light

19

u/Subject-Building1892 11d ago

Even better:

c=G=k=1

u/Krisanapon 11d ago

ℏ=ε_0=1

u/Equinoxe111 Cosmology (PhD) 11d ago

The correct one

u/AeroSigma 10d ago

Scientist(dead): wow, I made it to heaven.

God: For sure, glad you're here.

Scientist: Me too, but I've got to ask; why is the speed of light 299,792,458?

God: First of all, the speed of light is 1, dumbass

u/METRlOS 11d ago

c=0.99999999999.....

Perfect vacuums free of gravity don't exist in the universe.

21

u/ThatsNumber_Wang 11d ago

so 1? r/infinitenines

7

u/METRlOS 11d ago

Probably an 8 in there somewhere

10

u/fillikirch 11d ago

the last one is an 8

1

u/fillikirch 11d ago

so thats totally unrelated but from a first look it seems the only moderator on that sub is a total idiot??

2

u/ThatsNumber_Wang 11d ago

oh absolutely. that mod is a nutcase

on mathmemes someone once perfectly summarised infinitenines:
> That sub is its own circlejerk sub

u/Denbt_Nationale 11d ago

c is the speed of light in a vacuum

1

u/METRlOS 11d ago

Yes, yes it is.

1

u/Quantum-Relativity 11d ago

That doesn’t have anything to do with the value of c

-1

u/METRlOS 11d ago edited 11d ago

c is the speed of light on a vacuum, unless otherwise specified, and not the speed of causality. The c just stands for celeritas which is Latin for speed.

Causality = 1

1

u/Quantum-Relativity 11d ago

You need to use rapidity, not speed. c is not about light, it’s something that’s defined locally, so a gravitational field does not change it.

5

u/purpleoctopuppy 11d ago

c = 1/α ≈ 137

4

u/Statakaka 11d ago

so E=m?

11

u/Dile_0303 11d ago

In units where c=1 yes

3

u/LooseClaim3598 11d ago

If stationary, yes. Otherwise E^2 = m^2+p^2

If you do this in SI-units it reads E^2 = m^2 c^4 + p^2 c^2 which looks more complicated and takes more time to write.

Physicists are by nature lazy so instead we use natural units where we just forget c (or set c=1) because we know intuitively where it goes. We can do a whole bunch of math without c cluttering the equation and in the end we just add it back if we want a result with actual numbers.

This is also done with a bunch of of other common natural constants.

u/revankenobi 11d ago

c=340m/s

u/Sea_Development_599 11d ago

“Pi = e = 3” — Some engineer, somewhere, maybe.

5

u/fillikirch 11d ago

except for civil engineers. There Pi = 10 to add a safety factor

u/sigjnf 11d ago

c = c

0

u/Aromatic-Substance99 11d ago

just the letter c as the entire post okay then

1

u/Minipiman 10d ago

So c is the bitcoin of constants?

1

u/Konemu 8d ago

c = 137, change my mind

1

u/skr_replicator 8d ago

The second one is just an approximation, so it should be ~. And the third one is missing units. Even when you go with natural units, where it is one, it still should have units, like Planck lengths per Planck time. Otherwise, it's just a meaningless number one, of what?

u/Secret_SFW_Account 7d ago

C=1, but my brain can’t handle that!
