Myself and several other space engineers (+partners) are soon moving to Oxford / Didcot, as we're starting work in Harwell.
With Diamond, ESA and the university being nearby, I'm wondering if there are particular areas where physicists / engineers tend to cluster? Are there any specific areas...
Hi,
I've just got onto a PhD at Manchester uni and I'm looking for a house there. Is anyone else here in the same boat?
I'm looking primarily at Ardwick, Hulme, Withington and possibly the city centre - but open to other ideas though. I want to avoid Rusholme, Moss Side and anywhere...
I'm currently trying to figure out exactly why aromatics (e.g. polyvinyl toluene [PVT], polystyrene [PS], anthracene) fluoresce and scintillate...
I know that its got something to do with the pi system causing dense clouds of electrons to form in the ring(s), and that the addition of a...
Your problem there is that not all the converted mass becomes heat - some escapes as gamma rays. Also, the heat capacities aren't known anywhere near as accurately as they'd need to be! Nice idea though
Due to how our units are defined, c is fixed - its only dependence is the rate of ground-state Cs-133 hyperfine transitions. In trying to measure the speed of light, you're actually measuring how long a metre is!
Light travels 299792458m exactly (ignoring QED) in a vacuum, per second.

c is known exactly, as the metre is defined in terms of c and the second (which is defined in terms of the rate of hyperfine transitions in caesium-133 atoms).
c = 299792458 m/s exactly.
c can't be "measured" as such, as we know it exactly - when we "measure" the speed of light, we're...
lol yeah :D I've never blown a capacitor before, but had my fair share of transistors before I learned to bias them properly! Theyre boring though, they just stop working... no explosion.
All transistors should contain a little gelignite to let you know when you've messed up!
Amps are proportional to the amount of electrons flowing per seconds (charge unit
s per second)
Volts are related to the amount of energy each electron carries (energy per charge unit)
A normal PP3 (9V) battery:
connect the positive and negative terminals together and the positive will...
May be useful
This may be helpful, it may be completely wrong... you presumably understand it better than I do!
I've never been taught Fourier transforms, but I've read about them and used them occasionally - I can't quite make sense of you're data, but here's my basic understanding of FFT &...
Hi. I'm not actually doing an electronics course (Maths & Physics), but I have just finished building a 140W BJT guitar power amplifier and cabinet. I'm looking to build a FET-FET cascode preamplifier now, but am not too familiar with JFETs - So far, I've got:
