I'm making a lead sheet of the song "One" . I chose the key of Bb because the song feels the most "at home" when the progression lands there at the guitar solo after the 3rd chorus. You could alternatively say it's in Db, which is the first chord of the verse each time. I'd like to hear which one...

It is often said that the market is guaranteed to go up in the long-term, even if it may be shaky in the short-term.

The reason I'm asking... I have a relative (real 60s hippie/artistic genius) who does this all the time on FB, and FB doesn't understand that it's not his own opinion that he's expressing (albeit in an inflammatory way, for people who don't realize what it actually is). It's a form of protest for...

The primorial \$p_n\#\$ is the product of the first \$n\$ primes. The sequence begins \$2, 6, 30, 210, 2310\$. A Fortunate number, \$F_n\$, is the smallest integer \$m > 1\$ such that \$p_n\# + m\$ is prime. For example \$F_7 = 19\$ as: $$p_7\# = 2\times3\times5\times7\times11\times13\times17 = 5...

I just stumbled upon the definition of a map between to groups $$\varphi:G \to H$$ being a 1-isomorphism. It means that it is bijective and satisfies $$\varphi(g)^n=\varphi(g^n)$$ for all $g \in G$ and $n \in \mathbb Z$. So my question is: What is the smallest example of two non-isomorphic 1-isom...

How do we know that there are no blocks that predate the genesis block? A block that could potentially contain any number of coins. If somebody already created such a block from before the genesis but never published it could it (technically) stil be merged with the chain?

We were taught the long division method of finding square root in junior classes. The logic behind the method used to be unclear, it remains so even now! However, we learnt and practiced the algorithm well. To me it appears that the identity $$(a+b)^2=a^2+2ab+b^2$$ lies behind the method. Howeve...

If a bounded function $f$ is not defined on a finite set $A$ of numbers inside an interval $[a,b]$, is it Riemann integrable over that interval $[a,b]$?

Can we claim that for an orthogonal matrix $A$ (satysfying $AA^T=I$), its symmetric and skew-symetric parts are always commuting? Symmetric part is calculated as $S=\frac{1}{2}(A+A^T)$ and skew symmetric part as $K=\frac{1}{2}(A-A^T)$. It's easy to show the claim for dimension $2$. Also for dimen...

Maybe this is not possible to answer, but I was hoping there was some reliable information available on this. It seems to me that the SpaceX Starship rockets have sort of a homemade quality to them, like they were made in someone's garage with basic tools, vs even some of SpaceX's other rockets. ...
