Posted: 24 Mar 2017 10:08 PM PDT Why don't we use a cocktail of many types of antibiotics at the same time limit the chances of the bacteria developing a resistance? So say you had a sample of bacteria that was treated with 20 similar targeting antibiotics at the same time and a mutation existed in some of the population that caused them to have a resistance to antibiotic #1, wouldn't that mutant segment of the population still be wiped out by antibiotics #2-#20 and for any resistant mutant strain to develop and survive the treatment it would require a mutation that was resistant to all 20? Apologies if my understanding of the way resistances develop or any other misunderstanding of the subject. [link] [comments] |

Posted: 24 Mar 2017 01:31 PM PDT Looking at raptors and birds I can see a resemblence and imagine the dinos in feathers. But are there any scientific findings which would suggest the same has been true for sauropods or stegosaurs? I am sorry if its the wrong subreddit, but its something in between science and history.

Posted: 24 Mar 2017 09:58 AM PDT Of course the 3% may instead be 10%-20% or whatever, but I am curious why downloads take longer in certain sections of the package. Do some pieces of data really take longer or are the percentages inaccurate? [link] [comments] |

Posted: 24 Mar 2017 09:06 PM PDT IHello there. I still try to get my head around the nature of quantization, specifically about light. Since Max Plack, the energy (and from what I learned, also the frequency/wavelength) of photons is known to be discrete, right? Can someone explain to me, why physicist talk about the spectrum of light as a continuum? Is this not the case when the observed space is limited to small regions? Are superpositions of wavelengths possible for single photons, and do they possibly form a probablistic "pseudo-continuum" by interference between all the possible wavelengths? Please clarify, if you are referring to specific continuous representations i.e. the EM-field or a single travelling lightwave as a continuous / analytic description of a wave, or if you talk about the single photon as a particle (at a specific event, i.e. during emmission / absorption) or about something even more fundamental, such as superpositions, interference, etc. [Edit:] Another strange thought: Do relativistic effects / gravitational dilation (the doppler-shift) imply, that frequencies in-between must exist (with energies not divisible by Planck's constant), or is the net energy of a photon lorentz-invariant? I guess, there is still a lot of ignorance on my part, so please be patient with me. [link] [comments] |

How is the evaporation rate of a specific substance determined? Posted: 24 Mar 2017 02:36 PM PDT In other words, why do some substances evaporate at different rates than others? [link] [comments] |

How does a CCD or CMOS form an image? Posted: 24 Mar 2017 09:35 AM PDT I can't quite find the answer I'm looking for on this. I understand the operation of both CCD and CMOS detectors. What I don't know is how they manage to discriminate between pixels, and how their readout circuitry forms an image out of the information collected. [link] [comments] |
