    MATLAB API For Wave Flume Data Analysis

    (As a quick note, 'wave flume' should be taken rather generally. I basically just mean the sort of experiments involved in the flow of water which may use instruments such as pressure gauges, load cells, wave gauges, and ADVs. I know that they're not always done in a flume per say -- the...

    What data do toxicologists collect and how?

    I am woundering if there are any toxicologists on this forum so I could ask some questions (If they don't mind). For example, what data do you record on a day-to-day basis, how is it recorded and how it is made traceable. I have a rough idea, however I am not certain as I can't find anything on...

    Split Hopkinson pressure bar data

    Currently coding a wave separation script for the split hopkinson pressure bar. Is there a place I can get raw data for the split hopkinson pressure bar to test my code?

    Is there a byte that never occurs in a float?

    A float consists of four bytes. I am using a data stream of floats through radio. This data occasionally is not a float though, and sometimes I'd want to stop the logging of floats of the stream, by inserting a "stop char", which would be checked by the program. Previously I was using simple LF...

    Physicists set to revolutionize big data, AI

    When I opened up the article https://www.wired.com/2017/01/move-coders-physicists-will-soon-rule-silicon-valley/ I expected to see quantum computing as the next field physicists are to revolutionize. I was surprised to see it was data management and machine learning. I am happy for physicists...

    I Converting Planck data for spherical projection

    Does anyone know how I could convert data from Planck, which appear as an oval shape, into a form that I can easily map onto a sphere (ie. a rectangular shape in 2:1 aspect ratio)? Here is an example Planck image: http://sci.esa.int/science-e-media/img/61/Planck_CMB_Mollweide_4k.jpg I see that...

    A Redshift data on stars the same distance from earth

    Can anyone in the cosmology community direct me to hard research data that specifically demonstrates: there is no detectable redshift difference in stars that are the same distance from the earth but in all different directions. This is of course related to 'does the universe have a preferred...

    I Why does a kinked wire reduce data throughput?

    Hi. I read that every kink in a data wire reduces throughput. What's the physical reason for this? Does the resistance of the wire increase at a kink or is this an inductive effect or something else?

    Can there be insurance for data loss due to EMP

    If an insurer were to offer a policy against data loss from a catastrophic event such as an electromagnetic pulse, the insurer would be in no position to pay when the contingency occurs, the reason being that all of his own bank account will have been wiped clean by the same EMP. Therefore I...

    A Using quantum-secured communication for data transfering

    Hello! I am wondering if it is theoretically possible to allow a means of data transfer (or internet, etc.) by the idea of quantum entanglement. Correct me if I make any errors in understanding. But, by what I understand, in essence you could for instance run a computation on a quantum computer...

    Stargazing Help with telescope/observatory data and images

    I was wondering if anyone would help me get my hands on some telescope data and images of exoplanets. I know they must exist somewhere in databases on the internet, but I haven't been able to find them myself. It would be great if one of you could show me where I could get them or even if you...

    Getting into data science from computational physics?

    I'm currently working on a master's degree in physics where my project uses C++. I have read about how some physics phD's were able to get data scientist roles despite working on computational astrophysics. This is a little surprising to me since I thought experimentalists would be more suited...

    How to fit given function to blurred data points?

    Are there any elaborated theory or method how to fit parameters of a function family to data given by probability distributions of data points instead of given coordinates of points precisely without error? I think this is a very general problem, I hope it is already solved. Important: I...
