Explainer: how much carbon can the world’s forests absorb?
We are unsure how much the trunks of all those trees weigh, nor can we know for certain the weight of their roots. It is even harder to figure out how much the total global forest biomass grows from one year to the next - a key figure that tells us how ...
SOFTWARE & COMPUTING: BEAM ANALYSIS: The basics of Gaussian beam decomposition
This can certainly ... the synthesis of the final optical field. No one propagation algorithm works for every possible situation and so software developers strive to provide their users with useful and productive options. Gaussian beam decomposition ...
Seeing and awareness, or how fear can bypass the visual system
That article is just one ... can be unaware of seeing something, even immediately after being given a quick glimpse of it, yet behave as if they have seen it. We discussed how visual images can be “masked” — flashed quickly and then followed by ...
Chemists illuminate elusive mechanism of widely used click reaction
In fact, based on the new findings, Fokin and his team have begun to devise new reactions in which one copper center can be replaced with a different element, to pursue complementary biocompatible and efficient techniques.
The Time-Reversed Laser to See the Light
They work because in certain materials, the passage of a photon past an atom can trigger the release of another photon which goes on to release more photons and so on. This chain reaction generates ... lasing process works in one direction, why can ...
