Oh god... I've changed jobs and tomorrow is my last day. I think some have planned a leaving do thing near the end of my shift.

Do not want. I know there's a card. Not sure if cake.

Consider it a preview of your funeral service; unwilling guest of honor and all.

How strongly do you feel that? Most bosses where I am would listen if I said I really didn't want a leaving do. Depends on culture where you work, of course.

The other day I was following along with the course of a PF HW problem, when I decided to try something new, as distances involved varied by 5 orders of magnitude, from shortest to longest, and doodling a map where you could see all the lengths and lines and angles and distances seemed out of the question.

Drawing maps logarithmically, does not seem to work.

The thread had to do with eclipses, and I was trying to work out some angle for the edge of the penumbra to touch the earth.

Logarithmically, the moon is about half way to the sun from the earth.
But, measured from the sun...
Let's just say, that I'll not be trying this maths trick again.

ps. It did give me a giggle, when I ran across one possible explanation of how one of Frank Zappa's kids got their name:

 

[OmCheeto]

That maths problem did prompt me to finally work out whether or not god used logarithmic time.

As far as I can tell, she did.

 

[BillTre]

@OmCheeto, I like your "Ohm tries to interpret what "god" says happened" in your table.

In my opinion, this is a basic limitation of any ancient text's interpretation of modern concepts.
The guys back then, upon receiving God's explanation of the universe, did not have the conceptual framework in which they could have understood it (no chemistry, no physics (other than common knowledge, no biology).
Any knowledge they received could not have been understood.
Or if it was not properly communicated.

No comment on today's knowledge levels.

 

[OmCheeto]

I was just amazed that given only 2 time points*, that each 'god' day seemed to correspond so well to some actual Earth era/event.

big bang, day 1, 13.8 billion years

ps. I like to think that there might have been something to that old Star Trek episode: Distant Origin
Those Hadrosaurs came back 3000 years ago, told us what happened, and we've been arguing about it ever since.

Anyone who forgets about benefits of moderated sites , notice/remember the types of questions allowed in unmoderated sites:

"So, is it true all the novels ever written appear in the expansion of infinite numbers like pie ($\pi$)"?

Well, it would be wrong for $Y=Y_0+Y_1$.

Iirc, it has to see with the associated SES splitting.

Tv is not always bad. Just watched, i.e. listened to a lecture by a Harvard anthropologist about the decline of various civilizations (Maya, Easter Islands, a certain conflict in the medieval Japan, etc.). It was very interesting and completely up to date. He closed with the statement that he is cautiously optimistic, because nowadays we have several communication networks which allow us to learn from catastrophes elsewhere and elsewhen.

I was stunned as they said at the end that it was from 2005. I would like to ask him whether he is still optimistic.

Sad thing is channels like nat geo, discovery, which intended to provide serious programs ended up jumping the shark because,it seems, people today only want entertainment and not having to do any serious thinking.

That's the European luxury of having public channels which are paid per general fees. The only disadvantage is that they are broadcast at weird times. (We do not call it socialism here, we call it public interest of education and culture. We believe that our administration has the duty to keep the population educated, at least in principle. A cop once told me that people have the right to be stupid.)

Almost every country, AFAIK, has its own Public Television System, likely for that reason.

I cooked it because of your joke. Now someone has to run off the calories again. Since it was your fault ...

Time is often considered as a dimension on its own right. With all the confusing and disturbing quantum paradox-like experiments it just happened to me - how 'thick' is the 'present' actually?

I have always been curious to work out the topology of space-time, but was always too busy ( i.e., too lazy) to work it out, or even to look it up.

$7 for a 48h access and $72 for a download, only to see whether a paper from 1937 is the one everybody refers to when they say: "... proved 1937, that ..."

Ridiculous.

Doesn't your institution pay for access? Most "non-trivial" institutions get access.

 

[nuuskur]

Yeah, those prices are ridiculous. Thank god our uni pays for mathscinet and whatnot.

I get triggered every time I see an action denoted by $\lambda . v$, what's wrong with $\lambda\cdot v$? :( e.g multiplying vector with a scalar i.e ring action on an abelian group.

Multiplication is usually associative, an operation doesn't have to be.

@nuuskur : You're not the only lost one: After many times talking to the French Math guy I realized 'Lemons' is meant to be 'Elements'. And 'Roget' stands for $\rho .(j)$

Aren't updates optional beyond Win 8 or so? Or should you really do them, maybe for security patches?

I guess you can avoid them, but then they will get on your nerves with permanent reminders, and if you don't pay attention during shutdowns, installation starts. With W10 even the small rest of transparency has gone. In W7 I could still decide what to update and what not. E.g. I don't need their Java version (forgot how they name their nonsense, something with framework IIRC.) Now it's only update now or postpone it. And postponing it forever sucks. If my early Linux experiences hadn't been so troublesome I would certainly use Linux. But I only know the early versions where you had to be a Linux expert before using it. I always only used it from time to time, so I never get used to it completely. And I fear that I will end up with a Windows emulation in order to get all my old programs running. So I keep watching how W10 trashes my HD with big installations and braking the performance. I see the day coming I reinstall my W7 copy.

Careful if you use your Win7 for VMWare. I used a VM because I had Python 2 and 3 in the same machine and requests to the server end of either created conflict since it was not clear who was going to serve it.

Looks like I got hit by the same update yesterday. This morning when I tried to turn it on, it just sat there. I thought that maybe it turned itself back on after I left the room causing the battery to die. I guess when I get back home, I'll have to plug it in and let it think about restarting for an hour.

I don't know if my issue with win7 was caused by it being in the VM. Still, I doubt security patches are needed at this point since it is not likely it is still used by many. I respect MS updating it, just don't see a good reason to do so.

I was referring to a Windows 10 update. Unfortunately, security patches are a necessary evil.

I understand, but I am surprised people are still trying to hack into older versions of Windows?

 

[Borg]

Why? Those are the easiest ones to hack.

 

[fresh_42]

... and W7 was the last one you had a chance for a convenient customization. I still think that 2003 Server ed. was the best OS MS ever produced.

 

[WWGD]

Why? Those are the easiest ones to hack.

But less often used, i would think. I guess hackers would aim both ease and "market size".

 

[nuuskur]

I turned off all the automatic updates on my Win10 machine. Much better that way

My wife started the computer and left it run for 3 hours and it never started. Looks like I'll have to perform a Safe Mode debug fest. yippee...
