Because everything is so doom and gloom in the news, I just thought I’d share something from a review of the current (as of mid yesterday) vaccination numbers.

Right now we’re seeing about 200-250k positive per day which is starting to trend down for the last week, but we’re doing about 500,000+ vaccinations per day and going up (first or second doses - not necessarily fully vaccinated people, but jabs in arms). A few states have already vaccinated more people than total number who have tested positive. (source data and more here)

The UK has now given more people the vaccine than have tested positive in the country. ( A total of 3,559,179 people have received their first dose as of Friday, with 447,261 people having also receiving their second dose.) For the last 7 days the average is about 250,000 vaccinations per day, compared to about 50,000 positive tests per day.

Not to mention Israel’s efforts are freaking inspiring, and Denmark is leading the EU in (first shot) vaccination rates.

It’s important to remember that we have a long way to go, domestically and globally in all countries, that people are still sick and dying, and that we still need to behave ourselves and wear masks, social distance, don’t make unnecessary trips, etc., even if you are vaccinated. But this is some delicious fucking news.

And the 2018 Nobel Prize in Physics goes to...

I wanted to post something about the POTUS behaving with his usual misogynistic ways in press conferences, but instead, I decided to make post #2 of Fucktober about Donna Strickland, a woman in STEM, a fucking Nobel Prize winner in Physics.

The award puts her in esteemed company. The ONLY OTHER women who have received the Nobel Prize in Physics include Marie Curie and Maria Goeppert-Mayer, whose work was key in understanding nuclear energy.

In a statement after receiving the prize, Strickland said “We need to celebrate women physicists because they’re out there… I’m honoured to be one of those women.”

We need to promise to ourselves that we will change this and it will not be considered a fucking SURPRISE when a woman wins a Nobel Prize.

One half goes to Arthur Ashkin, Bell Laboratories, Holmdel, USA

“for the optical tweezers and their application to biological systems”

and the other half jointly to Gérard Mourou, École Polytechnique, Palaiseau, France | University of Michigan, Ann Arbor, USA and Donna Strickland, University of Waterloo, Canada

“for their method of generating high-intensity, ultra-short optical pulses”

Tools made of light

The inventions being honoured this year have revolutionised laser physics. Extremely small objects and incredibly rapid processes are now being seen in a new light. Advanced precision instruments are opening up unexplored areas of research and a multitude of industrial and medical applications.

Arthur Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. This new tool allowed Ashkin to realise an old dream of science fiction – using the radiation pressure of light to move physical objects. He succeeded in getting laser light to push small particles towards the centre of the beam and to hold them there. Optical tweezers had been invented.

A major breakthrough came in 1987, when Ashkin used the tweezers to capture living bacteria without harming them. He immediately began studying biological systems and optical tweezers are now widely used to investigate the machinery of life.

Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses ever created by mankind. Their revolutionary article was published in 1985 and was the foundation of Strickland’s doctoral thesis.

Using an ingenious approach, they succeeded in creating ultrashort high-intensity laser pulses without destroying the amplifying material. First they stretched the laser pulses in time to reduce their peak power, then amplified them, and finally compressed them. If a pulse is compressed in time and becomes shorter, then more light is packed together in the same tiny space – the intensity of the pulse increases dramatically.

Strickland and Mourou’s newly invented technique, called chirped pulse amplification, CPA, soon became standard for subsequent high-intensity lasers. Its uses include the millions of corrective eye surgeries that are conducted every year using the sharpest of laser beams.

The innumerable areas of application have not yet been completely explored. However, even now these celebrated inventions allow us to rummage around in the microworld in the best spirit of Alfred Nobel – for the greatest benefit to humankind.
