In English, many things are named after a particular country – but have you ever wondered what those things are called in those countries?
- Physicists have used ultrashort pulses of light to control the motion of electrons ejected from molecules and to produce electron beams just a few nanometres in length.
- Now physicists in Vienna and Germany have managed to do just that, allowing the carrier-envelope phase of a high-power ultrashort pulsed laser to be altered at will.
- Although the ultrashort solitons described above have so far only been generated using a GaAs: InGaAs laser, nothing inherent to the technique restricts it to a specific material system.
- If you use an ultrashort pulse of laser light instead of white light, the pulse will also break up, shedding smaller bits called precursors as it goes.
- In their experiments conducted at the Max Born Institute in Berlin, Ropers and colleagues aim an ultrashort laser pulse at a nanostructured metal surface.
- According to the uncertainty principle, these ultrashort pulses would have a very wide spectrum of energies - with some photons in the gamma radiation range, having more than 1 MeV of energy.
English has borrowed many of the following foreign expressions of parting, so you’ve probably encountered some of these ways to say goodbye in other languages.
Many words formed by the addition of the suffix –ster are now obsolete - which ones are due a resurgence?
As their breed names often attest, dogs are a truly international bunch. Let’s take a look at 12 different dog breed names and their backstories.
