Quantengravitation: Nachweis von Gravitonen scheint möglich

Mit einer neuen Versuchsidee ließe sich das postulierte Quantenteilchen der Schwerkraft mit aktueller Technik nachweisen

La myéline entourant les fibres nerveuses générerait des intrications quantiques

Une étude suggère que la cavité cylindrique formée par la gaine de myéline entourant les fibres nerveuses (ou axones) peut produire des paires de photons intriqués.

What Are Photons, Anyway?

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While q…

Neopixels? Try Liquid Nitrogen To Color Shift Your LEDs Instead

If you’re like us, you’ve never spent a second thinking about what happens when you dunk an ordinary LED into liquid nitrogen. That’s too bad because as it turns out, the results …

Bending Light To Fit Technology

Solar power is an excellent way of generating electricity, whether that’s for an off-grid home or for the power grid. With no moving parts maintenance is relatively low, and the downsides of …

Measuring Planck’s Constant With LEDs And A DMM

The remarkable thing about our universe is that it’s possible to explore at least some of its inner workings with very simple tools. Gravity is one example, to which [Galileo]’s incline…
