Hot today doesn’t necessary mean Cretaceous Climate tomorrow

We are now in one of the hotter summer until we have data, and affect all north hemisphere. The extreme climatic episodes has augmented in last years and it’s a prove the begin of climate change.  The most relevant effect is the growing of mean planetary temperature associate at the growing of CO 2 concentration. Both grows are simultaneous and the most preoccupant of them is that is making with exponential form. But can we affirm that the future weather will be the same of the Cretaceous age in a few years? The answer is not trivial. The growing of greenhouse gasses help to grow the atmosphere temperature, and the growing of temperature augment the concentration of this gasses, this fact is naming Feedback. Feedback is the main mechanism to guide the atmospheric processes. There are same studies that show the correlation of CO 2 concentration and temperature, and there are numeric models that demonstrate this correlation. This thing don’t mean that we had burned a lot of fossil...

The drop that makes a glass overflows

If you fill a glass until the top and the last section we do drop to drop, we reach a point where a drop enters the glass begins to overflow. We can consider that the penultimate drop completed volume of the glass and last drop did not fit and so it fell by the side. So just get out there would expect a drop, but in reality much more water overflows. This behavior is caused by the surface tension of the liquid that links the surface preventing it from breaking, thus the last drops before overflow don't fit but tension doesn't let water to fall by side. When it starts to overflow? So when the weight of the liquid is higher than the tension, the surface loses its mechanical consistency and breaks, it let out all the excess liquid. There are other metastable situations that after passing the threshold of stability, under certain conditions so close to threshold, it remains stable until they were disturbed or too move away to threshold. The instantaneous vaporization of water’s gl...
