Particularly pertinent to me right now as I'm in hospital sat next to my probably dying mother

Sorry to hear that- thoughts with you. Lost both Mum and Dad this year myself and it's tough.

 

[Lamp]

Yep sure is
Lost my Dad almost 2 years ago, and my Mum in July.
It changes you. Well it changed me
Makes you re-assess what's important in life and I'm not afraid of expressing emotion anymore.

I see the worrying consequences of assisted dying in other countries. Britain’s bill needs a radical rethink | Lucy Thomas

We need to completely separate assisted dying from healthcare if we are to avoid the errors made elsewhere, says palliative care doctor Lucy Thomas

I'm against assisted dying for this reason:


I'm a strong personality but would suffer unser that pressure. To get to the end of your life and be made, socially, to feel like a burden is an unconscionable recipe for a profoundly sad end.

I made it to 19.49 and admit I haven't the faintest idea what hes on (or on about).

I haven't the faintest idea what hes on (or on about).

Its homological mirror symmetry.

A Calabi Yau manifold ("X") can have a mirror manifold ("Y") such that certain properties of X correspond to certain properties of Y. Its useful in String Theory.

(I say useful, you need to have an advanced post-doc understanding of complex math. It is way beyond standard PhD level physics. We're talking Perimeter Institute level here !)

For example there is a category (called the Fukaya Category) associated with symplectic manifolds built from Lagrangian submanifolds and their intersections and captures the algebraic structure derived from the symplectic geometry of, say, the Calabi Yau manifold.

 

[TdC]

Ahhh! It all makes sense now!

You might as well be typing in REGEX.

Ok in English:

(@Zarjazz correct me if I'm off target here)


Some scientists believe there is more to our universe than the standard 3 spatial dimensions (up down, left right, forward and back)

They believe there is an additional 6 (!) dimensions. But you can't see them. They're tiny. And they're everywhere.

Imagine a sheet of wrapping paper. Now imagine scrunching it up into a ball. Well these extra 6 dimensions are scrunched up (or "compactified") in an analogous manner like the ball of wrapping paper but they are so tiny you can't detect them. Each of these scrunched up balls is a Calabi Yau Manifold. The design on the wrapping paper could represent Lagrangian submanifolds and intersection points referred to in homological mirror symmetry.

Within these "balls" particles such as electrons and quarks are formed by the vibration of tiny fundamental one dimensional "strings" (they can form open and closed loops) so small we have no way to detect them, and currently it is entirely theoretical, having no proof of its existence, hence its known as String Theory.

Ouch. My head hurts.

It all looks good to me, but I can sum it up as this is what you get when you give a bunch of bored theoretical physicists too many hallucinogenic drugs.

 

[Lamp]

Brain Greene is an excellent starting point for anyone wanting to get into physics and cosmology - but - he's a massive String Theory fan boi. I'm not sold on it. I don't think @Zarjazz is either (I don't want to put words in your mouth lol)

Sean Carroll is an excellent communicator too.

If I hear "manifold" and its not mechanical engineering I tend to stop listening 0_o

Just spent an hour unblocking the downstairs toilet
And its only 4am ! Fantastic

In the end pouring down a load of washing up liquid and pouring a couple of buckets of hot water did the trick

I'm gonna give the baked beans a miss for a good while...

Put a bin liner over a mop head and use it as a plunger, it'll shift your shit in seconds.

 

[caLLous]

Or buy a plunger because that sounds nasty.

 

[Raven]

An old bread knife also works.

 

[Tom]

I'm now a Bikeability instructor. Teaching primary school kids how to cycle on the roads. Not a main job, that's still TV, but a little side gig that hopefully will provide some respite when TV is quiet.

It's quite rewarding, if somewhat tiring.

Or tell the Mrs you've bought a goldfish in a bowl, and would she like to pet it (it has to be kept in the dark for the first few days so it can acclimatise...)

 

[Lamp]

You tend to get a lot of splash back with a plunger
We had a plumber come over once with one of those industrial plungers on the end of a 4 foot stick
It would have been less messy if he had ripped the toilet out and emptied it over the bathroom floor

Maybe I woke up extra grumpy today but there is no way these two should be winning the Nobel Prize in Physics. The wrote general purpose code, admittedly extremely useful code, but it does not increase our fundamental understanding of physics or the universe. Bah humbug.
