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 treat the very sick – and I urge politicians to vote against the deeply worrying assisted dying bill | Lucy Thomas

Helping someone to die should only be a very last resort, not a normalised part of our healthcare system, 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.

Stay strong Scouse

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.

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.
