University research and collaboration with companies

This article is a bit confused it uses example of steel developed at Cambridge as the example of a component where University research has contributed to the airplane engine (correct) and then talks about how Rolls-Royce benefits from its network of University Technical Centres (UTCs) (also correct). However I don’t believe that any of the UTCs have competence in steel design, that work was done in  Harry Bhadeshia’s phase transformation and complex properties research group in Cambridge. This shows how Universities and Companies benefit from being flexible in their approach to collaboration.

Penguin Awareness Day

The Telegraph has marked Penguin Awareness day with a quiz. I was shocked to find out just how little I know about penguins. It really makes you think. The quiz can be taken here: How aware of penguins are you?

A Christmas, String Lights, Story

I bought some LED string lights before Christmas and we had them in the office, for some random cheer. The lights were mixed colours, red green and blue. They were powered by two AA batteries, and we left them on continuously for more than a week. After a while I thought some of the lights were broken but later someone else pointed out to me that only one colour remained lit.

Only green LEDs for Christmas?

Only green LEDs for Christmas?

With only the green LEDs apparently lit, the voltage measurement on the battery was 1.153 V (1.156 V with no current flowing). A fresh battery capable of lighting all the colours of LED provides a voltage of 1.311 V with the current flowing (1.325 V with no current flowing).

Strangely green LED’s are the least efficient colour, so it’s strange they would be the last ones lit…

For change in voltage, red LEDs take the least to work, and as the colour moves up the colour spectrum toward blue, the voltage requirement increases (green is between red and blue).

Approximation of spectral colours on a display results in somewhat distorted chromaticity — Wikipedia

So does this mean these LED’s aren’t really naturally green ones, and rely on phosphor filtering? Or some other technology?

Is this a problem of perception of brightness of different colours?

These long forgotten 80’s track seem eerily familiar.

The Royal Society put together some student resources on Inspiring British scientists with minority ethnic heritage. My Supervisor Harry Bhadeshia is twice as inspiring as the rest, as you can see from the Royal Societies Tweet:

Among the Yamabushi (Narrow Road Part 4)

Victoria Vardley on Matsuo Bashō, with some beautiful sketches.

Back on the road with Bashō and his straw sandals…

One of the high points of his journey, figuratively as well as literally, was his pilgrimage to the 出羽三山(でわさんざん) Dewa Sanzan, three mountains of Dewa Province, which is a very sacred place in Shintō and Buddhism and in the 修験道(しゅげんどう) Shugendō mountain ascetic sect. This is a syncretic religion combining elements of Shintō and Buddhism, Taoism and other beliefs. Practitioners are known as 修験者(しゅげんじゃ) Shugenja or 山伏(やまぶし) Yamabushi (someone who prostrates himself in the mountains – the ‘bushi’ here is not the same as the word ‘bushi’ 武士(ぶし) meaning ‘warrior’). They go on foot through the mountains practising austerities, for example meditating while standing under ice-cold waterfalls – perhaps familiar to anyone who has read Mishima’s Sea of Fertility tetralogy? (Here is an interview with a Shugendō practitioner explaining some of the practices and the philosophy behind them.)

The three…
