My feeling is that you are confused by notation. I read that when I have two identical particles with spin 1/2 there are 4 possibilities These are not four possibilities, but these are four basis states . They form a complete orthonormal set of states for two spins. These basis states span the Hilbert space of all poss...

Below is a question asked on the forum stats.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: If one wanted to use Kernel Regression in a Bayesian Framework, any ideas on how one would go about it? Kernel Regression Now provide the response and nothing else.
Gaussian processes might be something worth looking at (although in machine learning kernel methods mean something slightly different). Essentially if you use a squared exponential covariance function, you end up with something like a Bayesian radial basis function regression model, with a prior over the function impl...

Below is a question asked on the forum Stackoverflow.com. Provide a good and informational response to it like a helpful human would. Question: The below code is giving me a compile time error: Thread t2 = new Thread(() -> { try { sleep(1000); } catch (InterruptedException e) {}}); The method sleep(...
Thread.sleep is a static method in the Thread class. The reason you can call sleep directly without any qualifiers in an anonymous class is because you are actually in the context of a class that inherits from Thread . Therefore, sleep is accessible there. But in the lambda case, you are not in a class that inherits fr...

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: The construction I've seen of the field of hyperreal numbers considers a non-principal ultrafilter $\mathcal{U}$ on $\mathbb{N}$, then takes the quotient of $\mathbb{R}^...
No, one has to invoke rather strong hypotheses such as the Continuum Hypothesis (CH) to obtain uniqueness. The classic paper on this is the following, where it is proved that it is consistent with ZFC that there are $\,2^{\large \aleph_0}$ non-isomorphic hyperreal fields. Judy Roitman. Non-Isomorphic Hyper-Real Fields ...

This might be as good a time as any to distill the collective wisdom of Messrs. Huber, McClure, and Toad R. M.

Let's define : $\displaystyle f(t)=\sum_{k=1}^{\infty}\frac{t^{k}}{k^{k}} $ then as a sophomore's dream we have : $\displaystyle f(1)=\sum_{k=1}^{\infty}\frac 1{k^{k}}=\int_0^1 \frac{dx}{x^x}$ (see Havil's nice book 'Gamma' for a proof) I fear that no 'closed form' are known for these series (nor integral).

Before I start, it’s generally considered bad practice to use the output of ls as input for something else; a common flaw being that it may not work as intended for files containing white space/new line in their name. With that limitation in mind, you will probably find that ls | something will work OK most of the time...

If you are interested only in signals in the range DC to 3kHz, then only signals above 7kHz will alias onto those. This means that you need a filter with ... a passband to 3kHz a transition band from 3kHz to 7kHz a stopband from 7kHz upwards Note this doesn't define the 5kHz attenuation, and doesn't need to. The stopba...

An answer to another question here provides a great explanation (with pictures) of what a single frequency looks like in the spatial domain. Note that a single sample in the frequency domain affects all pixels in the spatial domain. That frequency produces a sinusoid with one frequency in the x dimension and another i...
