Blackhole driven explosions

And the dynamic universe
Prof Carole Mundell started in 2007 as prof in Bath

Sun is an ordinary star. Gives us life.

Light colour of distant galaxies tells us about physics of stars. Such as Doppler shift and whether stars are new bright blue stars or old dying red stars.

Cro magnon man drew cave paintings of constellation. Such as Taurus the bull or Orion with a planet crossing it's path leading to a new feature.

Kepler saw moons about Jupiter. Took his gamma ray burst data. Found a pattern for the planets orbit.

Stellar mass black holes a few miles across 300 times mass of our sun collapse at the end of their lives.

Shadow of a black hole. Detecting a black hole: detect mass falling in to black hole such as stars and gas and their movements due to the gravity.

Merlin massive radio telescope near border with Wales. Auger network of detectors in S America.

Non-stellar AGN emissions massive jets of particles and gas emitted explained by black hole.

Spinning disc of light acts like a lens turning light beam passing through it into a laser. Black hole evidence. The water is moving at great speed so that the light beam gets red shifted by 500m/s on one side and emitted as laser beam while on the other side it is blue shifted by 500m/s and there is gain in the system through the energy added by the gravity of the core and other energy gained from system and we can detect this from Earth.

GRB (Gamma Ray Burst) afterglow allows a detection as light fades away over days after gamma ray burst. This is a powerful tool as we detect energy of entire sun over its whole life in a few seconds.

GRB robotic followup as it is such a fleeting event and easily missed by casual observer.

Prof Mundell likes to talk about magnetic fields. Fireball magnetisation. Detecting polarisation of observed light beam to detect magnetic field so polarisation is a magnetic field driven process. Remarkable how magnetic fields survive for so long after initial explosion.

Shrimp has 2 bit low light imaging in its eyes which is a great basic detection set up for astronomy!

Invited to do PhD when she interviewed for masters and is now head of physics at University of Bath.

LETTERS TO BEN: National Careers Service

Dear Ben,

Please find forwarded below the helpful advice I received from the National Careers Service RE compensation, which mirrored the advice Sue and Shirley offered after our meeting today. I hope I am communicating with you clearly enough that I want more money and more satisfaction from life, I want jobs to be easier and the girls to be easier as I currently feel frustrated. I don't feel I should have to do any more work to get it other than to raise this complaint at this point.
The thing I am most looking forward to is the rugby world cup in 2019 in Japan which I plan to go to with friends.
Regards,
William
Thanks. In reply to your email, the following information might be helpful to you.  
Your CV and cover letter look fine and you have some good work experience. Have you been keeping an eye on Hinkley point (near Bridgewater)? Here in the South West that is probably the biggest ongoing potential nuclear project at the moment and you could send a speculative CV to EDF energ…

Camden Crescent and Hedgemead Park

Here are my thoughts: Did you know that Camden Crescent, originally Camden Place and Upper Camden Place (which is now round the corner) was named after the Earl of Camden, Charles Pratt, who was Chancellor of the Exchequer so sponsored the scheme with his symbol on every door and crest of the exchequer on the decoration at the centre of the crescent? Charles Pratt was actually lord of Camden Place in Chislehurst in Kent. He was mates with William Pitt the Elder from Eton and Cambridge days. It was built 1788-1792 by John Eveleigh the architect.  One third of the 22 house crescent collapsed during a landslip which claimed 136 houses on the slopes of Lansdown Hill leading to the creation of Hedgemead Park below Camden Crescent. John Eveleigh was notoriously bankrupted in Bath, being called to the coffee shop in the Bath Chronicle by his creditors. Earl Camden was famous for supporting Fox’s Libel Act of 1792 which said that libel should be tried as murder with a jury regarding the poin…

Notes from Energy & Utility Forum 2017

1.Robert Symons, CEO of Western Power Distribution said: “Energy demand could rise by 100% by 2030. Smart grids will be needed to manage electric vehicle charging so that the usage does not exceed the supply capacity at any time during the day.”
2.Spoke to Harry Vickers, Business Development Manager of Camborne Energy Storage, Camborne Capital at the Energy and Utility Forum in London on October 23rd 2017. He told me his company is working with Elon Musk to bring Tesla battery grid storage solutions to the UK.
3.Spoke to Sally Barrett-Williams, Chairman of Energy and Utility Forum on October 23rd, who said subsidies for solar projects had ended and her company’s focus has shifted to energy storage schemes.
4.Spoke to Simon Dowland, PhD, at 13:00 on Sunday 29th October, Simon is now working up in Cambridge at the Cavendish Physics Laboratory at the University of Cambridge, he is working in industry for the company Eight19 Ltd a spin off from a research project to bring new technology …
