On watching this video, students should be able to: Distinguish between an observational and experimental study. Explain the main reason why a randomised experiment can if done well, be used as a test ...

When researchers compare these experiments to neutron-star observations, they can calculate the equation of state (EOS) of particles interacting in low-temperature, dense environments. The EOS ...

Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

With the aid of continuous observation, and a grant from the Royal Society for experimental purposes, he has been able to throw much light on these curious ponds. He shows that “dew-pond” is a ...

In many settings, however, such experiments are expensive and time consuming. Hence, it is desirable to obtain causal information from observational data, that is, from data obtained by observing ...

Presenter 2: In this film, we will look at how to collect valid measurements when we carry out an experiment. Presenter 1: For example, I want to investigate the distance a car travels when the ...
