This post confuses me. Why would code be simpler than the math notation? Both involve symbolic abstraction of basically the same complexity

The language physicists use in describing this is the following: “The electron can turn into a virtual photon and a virtual electron, which then turn back into a real electron.” And they draw a Feynman diagram that looks like Figure 4. But what they really mean is what I have just described in the previous paragraph. The Feynman diagram is actually a calculational tool, not a picture of the physical phenomenon; if you want to calculate how big this effect is, you take that diagram , translate it into a mathematical expression according to Feynman’s rules, set to work for a little while with some paper and pen, and soon obtain the answer.

The emphasized part of this paragraph is such a good point. The way we talk about Feynman diagrams makes many students and working physicists think of them as representations of the actual physical process that is happening in QFT. In reality they are just graphical tools for representing the calculation of a power series (either formal or asymptotic).

Given your usage why would you even compare the cost of your car to the cost of a monthly pass? Most bus passes are calibrated to make sense for people using transit as their primary means of transportation. You use your car much less than that, so to make an apples-to-apples comparison you'd need to compare your car costs against the same number of trips on transit.

I'm surprised that your insurance and gas cost is so low. A TTC monthly pass is only $156. You must have very cheap insurance and use only a small amount of fuel.

I think we should all be assuming that these are not real figures. I support Ukraine but would never actually believe these numbers. Disinformation is a weapon of war

I agree with your overall point but not the metaphor. Printing is more like using hand tools than cursive is, given it is slower and less mechanically efficient.

I personally write almost exclusively in cursive. Printing always felt so much more unnatural to me given that it requires lifting your pencil far too often. All of your time is spent lifting and resetting your pencil.

Having said that, I know my feelings on this are outside the norm. And I know for many it is seen as having a steep learning curve.

There are shockingly few stable jobs available in academia. People churn through years worth of short-term, underpaid contracts in the hope they can eventually land something better. But the reality is most don't.

What about lending? The key economic function of banks is transforming liquid customer deposits into longer duration loans.

I have bad news for you...
