Elon Musk Explains How Falcon Heavy Will Change Space Travel

Submitted by: littlemissqt 1 week ago in News & Politics Science Tech


SpaceX’s Falcon Heavy rocket took off from Cape Canaveral, Florida yesterday carrying its first payload -- a red Tesla roadster -- into orbit. Loren Grush spoke to CEO Elon Musk about the launch and what this means for the future of space travel, as well as Planetary Society CEO Bill Nye. The Falcon Heavy now holds the title for the world’s most powerful rocket, and its launch marks the first time a vehicle this massive has ever been sent up by a commercial company.

I did a big explanation on the equation post, but all the comments got wiped. I don't know if you had a chance to read it, so here it is again:

I feel like this would be a fun conversation to have in person. Really hard over the internet. I hope I'm not angering you, I'm just trying my best to explain.

Let's try this.

1. You say 6÷2(1+2) is the same as 6/2(1+2) is the same as:

    6
--------
2(1+2)

Correct?

2. You also understand that the order of operations means multiplication and division have to be done before addition and subtraction right?

3. So what if the equation is 6+4÷2*10? That's the same as 6+4/2*10 right?

So you're saying it is also the same as:

  6+4
--------
2*10

Written as a fraction that equals .5

However, when done properly with order of operations:

6+4÷2*10=

6+8*10=

6+80=

The answer is 68. 68 is the only right answer for the equation. It isn't an either or proposition. That is why you can't just turn an equation with a division sign into a fraction.

That make sense?

holygod Ok! This is what I replied to, but my PC froze while I was looking for a funny video to include in the comment. So I never sent it and now cannot get back there :p

3. Obviously that equation is entirely different. Clearly it is NOT 6+4 ---- 2*10 because it isn't written that way. It is 6+ (4/2) x 10.

BTW: I found it amusing that:
4÷2 = 2, not 8

and that 6+80 is 86... not 68 :-) LOLZ! Was that intentional or just late night typing?

The answer is 26, there is no ambiguity: 6+ ((4/2) * 10) = 26
With extra, superfluous brackets to highlight the only possible order of operations.

2. In maths you ALWAYS have to resolve the Numerator (top) and Denominator (bottom) of any fraction before doing any of the rest. I read it as 6 ----- 2(1+2) so I resolve the Denominator to = 6 and am left with 6 ÷ 6 = 1

It depends on what the equation is MEANT to represent, something we do not know! Unless more information if given, SOME people will mistake it for the "wrong answer" NOT because we are stupid subhumans who cannot read nor write. But because it is simply NOT clearly written IN OUR OPINION. Is it 6 divided by the sum of 2(1+2) OR is it 6 divided by 2 TIMES (1=2)?

If there is ambiguity or un-clarity it is the fault of the writer, not the reader.

"Do you need help with suicide?"
Now 99% of the population will understand that's about suicide prevention even if the word is omitted. BUT what if it were an advert for Dr. Kevorkian? Then it means help with committing suicide, right? Same exact words, entirely different meaning! You cannot claim the 1% are 'stupid' because they 'read it the wrong way' because they did not. it could be that the 99% are in the wrong, and it really is an advert for assisted suicide, we don't know!

The recording I was looking for is "George Sanders School Of Suicide" (aka: Commercial) by Maclean $ Maclean from the record 'Bitter Reality' :-) But alas I can't find it anyplace.

5cats I agree with you about the ambiguity if the "/" sign is used. But it wasn't.

toetagmodel2 Tried to explain it at the top. We were having an interesting back and forth on the equation post but the whole comments section got deleted somehow. So I replied on this post that didn't have any activity in case he wanted to keep it going.

Helium moon mining within 20 years imo.  But it won't be Musk.  The guy burns through cash faster than a premium hooker with special skills.

 These four words.

 Death  - to - the.... I mean, Van Allen Radiation Belt. Nasa and Space X and a complete tax payer money dump that creates the hidden class of people so rich you couldn't begin to wrap your mind around it.

I'm hoping to see private sector space stations or lunar bases in addition to the various launch vehicles. There's PLENTY of lucrative operations in space. I still have no clue why people don't see the incredible profit potential out there.
Lunar regolith mining, Asteroid mining, orbital micro-gravity manufacturing... The possibilities are nearly endless.

squidbush it's almost like we can't really get there, huh?

I like the idea of private companies commissioning private sector launch vehicles to send up science missions.
