My right hand might have lost its cunning, but my tongue hasn't yet cleaved to the roof of my mouth
Four-Song Peel Session of ska band The Bodysnatchers from April 8, 1980. Includes the song "The Boiler". Length: 14:00. #Ska#SkaMusicm.youtube.com/watch?v=kyhD...
Such a shame, one of my favourite eating places when I lived there.
They had a dish that they claimed involved a hundred spices. We asked if it was free if we named them all, needless to say we couldn't
Tonight at 9:45pm UK time, I'll be appearing on a BBC Radio 3 programme by John Foxx on "The piano of the future". Will also
be available for streaming after the live broadcast: www.bbc.co.uk/programmes/m...
"It may be of interest to mention that the European engineers have been using for many years a term,
which in translation would be called "pointer" (referring to the pointer or hand of a meter or a clock)."
The earliest reference the OED gives is a 1944 letter to Proc IRE, which doesn't use complex numbers but does refer to "the instantaneous angular velocity of the voltage phasor"
A footnote adds that " The term "phasor" is preferred for vector, which thus could be reserved for exclusive use in the vector analysis. The term "phasor" is used by the American Institute
of Electrical Engineers."
"... as it allows us to represent the alternate current , the sine-function of time, by a *constant* numerical
quantity , and thereby eliminates the independent variable "time"
altogether from the calculation of alternate current phenomena"
So he was using complex numbers to represent sinusoidal signals (and not rotating points). But he didn't use the word phasor, here or anywhere else I can find.
Wikipedia says that Steinmetz ("the most valuable piece of apparatus General Electric had" - dos Passos) introduced phasors. He certainly introduced the idea in 1893 at the International Electrical Congress in Chicago
His paper begins "In the following , I shall outline a method of calculating alternate current phenomena , which, I believe, differs from former
methods essentially in so far,..."
My strong preference is for the first definition, so that a phasor is a complex number with no time-dependence, not a rotating point on the complex plane
Furthermore, if v(t) and i(t) are voltage and current signals, both sinusoidal and with phasors (defn 1) V and I, I would say that the impedance Z = V/I (a complex number with no time-dependence by either definition) is not a phasor, because there's no signal Re{Z exp(j omega t)}
Annoyingly it's used in two senses - if a sinusoidal signal A cos(omega t +phi) = Re{C exp(j omega t)}, some people call C the phasor, while others call C exp(j omega t) the phasor
My review of The Experiment is now the most read article on the whole of The Guardian website.
It is genuinely one of the most shocking, disturbing, and timely things Iโve ever watched. www.theguardian.com/tv-and-radio...
There's a story that Weinstein greenlit Boondock Saints because he despised Duffy and could see that success would make him humiliate himself - did the BBC do the same to Rajan?
I gave a talk at EMF titled "Men in Tech #YesAllMen", in which I told my experience of being a woman in tech. I was afraid to publish it in case it affected my current or future employment.
With all the current news I would like to add my 2ยข. So here is the recording: youtu.be/WXL6K1lhvt0?...
Some years ago, in a fit of enthusiasm, I installed Linux Mint on an old laptop, and every few months I boot it up, install all the upgrades, and then pressure of work makes me go back to my Windows one. I've basically got a fancy Tamagotchi
1. Possibly their best song ever.
2. Rarely done live.
3. Was not a hit (should have been massive).
4. William Walton wrote to Pete to tell him how impressed he was.
5. Pete lost the letter.
Yeah anyone with an energy-related disability can let you know, if we donโt let our disabilities stop us, we can completely ruin our ability to function at all, sometimes permanently.
This is incredibly sad. I once interviewed RJ Mitte on the Southbank and he was very friendly and joyful on a sunny day by the river. He leaves a legacy of disability representation on the screen; something that is far from easy to achieve and still too rare. www.theguardian.com/culture/2026...
