(via SciShow) Most science experiments take a few months or years, but some take a whole lot longer. Here are six of the longest-running experiments of all time, including one expected to last 500 ...

If “art for art’s sake” is a desirable slogan, why not “science for science’s sake”? Modern scientists, whose goals are apt to be shaped by armed forces’ research grants or a corporation’s search for ...

Have you ever imagined the solution to a logic problem instead of calculating it? Such “thought experiments” are carried out using one’s imagination rather than doing actual research. Typically ...

A photon enters a cloud of atoms and emerges on the other side. When physicists calculate how long the atoms remained excited because of that transmitted photon, the answer falls below zero.

In the fast-paced world of laboratory science, the demand for analytical methods that are not only accurate but also robust and efficient has never been greater. The traditional approach to method ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

A University of Toronto experiment showing that photons can spend a negative amount of time inside a cloud of atoms has been published in Physical Review Letters, clearing peer review more than a year ...
