Know your scale – Why wavelengths are so important

So you thought there is just one “seismics”? In general, we might say that the seismics experiment is watching mechanical waves travel through Earth and then apply science on it to get an image of the Earth’s interior. However, this experiment and the science behind it has a high degree of uncertainty. When we conduct […]

Amazing fluid dynamics

Fluid dynamics is just boring equations, right? Well have a look at this video and think again! Food-dye is always fun, especially when you get to mix it and get some colourful joy. But this is just amazing how this liquid creates “laminar flow”. If there were turbulences in the fluid while turning, you would […]
