NASA's OSIRIS-REx probe will snag a piece of an asteroid Tuesday! Here's how to watch. | Space

Good pickup, Galu. I'm up for that. 6PM UK start and 10PM the main event Tuesday. Could be a late night...

SpaceX are doing something on Friday too.

Interestingly, the name 'Bennu' was given to asteroid 101955 after being selected in a "Name That Asteroid" contest held by the University of Arizona!

Students at the University of Glasgow would simply have named it 'Asteroid McAsteriod Face!

Apparently, only about 5 percent of numbered asteroids have been given names.

"This statement is False"

I looked it up. It's the liar paradox.

Liar paradox - Wikipedia

It's both true and false apparently. Hmm... gives me a headache.

It gives YOU a headache? Think of the androids ...

Harry Mudd is in Star Trek discovery, IIRC.

A friend of mine had a Star Ship named after him in a Star Trek online competition...

Jeremy or Jezar as he called himself hatched up the Loknan Class V Frigate USS Jezar.

I think I saw it getting blown up by the Klingons in the recent Star Trek Discovery series.

Lots on the BBC about this probe:

The Japanese have already grabbed a bit of asteroid dust:

Hayabusa-2: Japan spacecraft leaves asteroid to head home - BBC News

The recently launched Mars Rover is hoping to get a lump of rock back too:

All clever stuff.

Harry Mudd is in Star Trek discovery, IIRC.

Harcourt Fenton Mudd was a swindler and con man who appeared in Star Trek, the original series.

'Mudd's Women' is one of the more memorable episodes in which Harry uses the illegal Venus drug to make three women look beautiful when, in fact, they are not.

 

[Galu]

Think of the androids ...

Yes, burn out time for Norman and a temporary shut down for Harry's court of servile female androids.

And then the comeuppance for Harry Mudd as he is left behind on the planet with multiple android copies of his constantly nagging wife Stella!

It's both true and false apparently. Hmm... gives me a headache.

This seem to be the general understanding... but I'm not so sure. I think one have to distort the semantics, context and perspective to come to that interpretation.

1) See the whole sentence as an variable of type boolean. This means that all the letters "This statement is false" is the identifier of the variable. The value of the variable can be either false or true. This leads to that the variable is undefined as we cannot see an assignment of said variable and thus, no paradox is at hand.

2) "This statement is false" - it's true that that statement is indeed false. From an observers (2nd party) of the sentence perspective, there is no reason to believe that the 1st part, expressing the sentence, is lying. So it's a truth-full statement - i.e. it's true. But in no way is the object, i.e. the semantics of the expression both false and true at the same time.

It's just that the perspectives has been mixed up - like a word game... Whats the controversy?

QED

or where dod I go wrong - I'm sure I did.

Perspective is everything

[system7]

There's an old wise saying that where you sit determines where you stand. In other words, not only are there two outcomes, but two viewpoints.

This was considered Lieutenant Uhura's (aka Nichelle Nichols) 5th. finest performance by Trekkies.

After which she got cheerfully lifted physically off her feet by the shoulders by that old reprobate, Captain Kirk.

TBH, Kirk would probably end up in Court these days. But, IMO, it would have been worse if he had done the same to Scottie or Bones.

While waiting for this exciting Asteroid probe to attempt something quite difficult, I have been beavering away at another interesting Maths puzzle:

Quanta Magazine

There is a mysterious 10-digit decimal number, abcdefghij. Each of the digits is different, and they have the following properties:

a is divisible by 1
ab is divisible by 2
abc is divisible by 3
abcd is divisible by 4
abcde is divisible by 5
abcdef is divisible by 6
abcdefg is divisible by 7
abcdefgh is divisible by 8
abcdefghi is divisible by 9
abcdefghij is divisible by 10

What’s the number?

I didn't get it. I had a bash with Factorials, and 10!, but that was hopeless.

But I get the solution:

On Brilliant there are question related to this number. This number can found out without hit-n-trial method.

Clearly the 5th and 10th digits are 5 & 0 respectively,

Now 4th digit can only be from 2 & 6 as 3rd digit is odd and for the number to be divisible by 4 its last two digits must be divisible by 4,

Sum of first 3, next 3 & next 3 digits must be divisible by 3,

Hence,

We get the following combinations for 4th,5th &6th digits - 258 or 654,

Now with use of divisibility of 8 we can figure out 6th,7th & 8th digits,

With help of less hard work we can figure out the number.

As a betting man, if NASA can pull this one off, I'll be surprised.

One of the episode's themes is how people perceive reality and how they remember events.

It's also an episode in which Data, in true android fashion, insults Picard’s painting by giving it a fair and accurate analysis.

Any relation to people and events in this thread is purely coincidental!

Hardly a flattering painting:

And I know me Art.

I hardly think the Artist's Muse is gonna like it.

Anyway, the rocket is out of the stalls in an hour and a half:

I think it's gonna crash. But I've been wrong before.

 

[TNT]

Exciting. The last one took a while to find after a few unfortunate bumps

[system7]

It's super-exciting in modern Parlance.

My feeling is that NASA may not have considered that there is nothing holding this Asteroid together in Gravitational terms. It's a loose cloud of dust. So much that can go wrong.

Anyway, Time will Tell.

 

[Galu]

NASA coverage of the Bennu sampling starts at 5pm EST or 10pm BST.

I hope to watch it here: NASA Live | NASA

Is that where you're tuned into Steve?

 

[system7]

Nope. I've run into a technical problem with NASA.TV.

They seem to use horrible Adobe Flash.

But if I can't hack it, I might as well give up.

Currently on Al Jazeera and HTML5.

I still think this spacecraft might run into problems. 5 minutes to go.

 

[Galu]

I'm watching the commentators right now. NASA Live | NASA

Both commentators are wearing face masks which are made of transparent film so you can see their mouths as they speak. The masks are sealed around the nose and chin with what looks like white foam strip.

Where can I buy one?

Due to low data rate, real images will not be available for a few hours and after the probe has backed away from the asteroid. Currently, we're only going to see time-matched simulations of events as they happen.

Guess I'll bow out for now!

 

[system7]

Probably a wise decision. I think we should look in tomorrow to find out how it turned out.

The Americans just keep us up before our bedtime.

But i still don't fancy their chances.

 

[benb]

Well, the probe says it did it, but can you trust a comm link that's 40 bits per second?
