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.

80s tracks

These long forgotten 80’s track seem eerily familiar.

Among the Yamabushi (Narrow Road Part 4)

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…

Compiling Fortran

Mixing of Fortran types occurs, and often results in problems when mixing free-form Fortran with older styles of Fortran, and when using different compilers.

As pointed out at Geek Tricks.

In Fortran 90/95, a “&” at the end of a line, or in the front of a line, is treated as line continuation sign. But in Fortran 77, it has to be a character at the sixth column. In the code I get, most “&”‘s comply to the Fortran 77 format, but some are not. So I move all “&”‘s to the sixth column, and now the code compile with gfortran.

If you want to replace lots ampersands from the ‘first column’ to the ‘sixth column’ on a lot of lines you could use ‘sed’ string editor to do that.

sed 's/^&/ &/g' input.f > output.f

You also need to check for lines which are too long in your input.

Many errors can be suppressed for now, with command such as gfortran -std=legacy output.f -o justwork

The Space Group List Project as a Poster

Would also make a good bed sheet or pillow case…

The Fascination of Crystals and Symmetry

The Space group list project ‘230’ – a collection of examples containing at least one crystal structure for all of the 230 space groups – is now available as a synoptical poster (size DIN A0, 84.1 x 118.9 mm):

Feel free to download and share the PDF!

If you print the poster on canvas you may use it also as a special shower curtain 😉
