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

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 Thomaswww.theguardian.com
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 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.

Ouch. My head hurts.Ok in English:

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.
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.
Put a bin liner over a mop head and use it as a plunger, it'll shift your shit in seconds.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...
An old bread knife also works.
You tend to get a lot of splash back with a plungerOr buy a plunger because that sounds nasty.

Geoffrey Hinton and John Hopfield share Nobel Prize for work on AI
Two scientists share the Nobel Prize for Physics for their work on machine learning.www.bbc.co.uk
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.
