The minimum depositional ages for each site as determined by zircon U-Pb geochronology are presented as vertical bars, with the width of each bar representing the 2 s uncertainty; in the case of Steep Rock,

We investigate the difference in the fraction of cells consumed by so-called extinct versus established virus infections, and find that this distinction becomes biologically meaningless as the probability of establishment approaches zero. We explain why the...

So we see that to get from one point to another in the least time when the ratio of speeds is n , the light should enter at such an angle that the ratio of the sines of the angles θ_i and θ_r is the ratio of the speeds in the two media. 莴苣斋注:这个推导过程很费曼!如果是...
