I left school with my STEM degree thirty years ago and I assure you it was difficult to get a job right out of school back then as well.
fast food prices keep going up and up and portions keep getting smaller and smaller....
This is the exact opposite of my experience.
If only there were some way to transmit the power to a place with hills...
You subtract it because P(A) + P(B) over counts by P(A and B)
the "flash crash" of 2010 was exacerbated by loss of liquidity as automatic traders pulled out because volatility exceeded parameters.
Humans panic. Computers don't.
Boy. That sure looks like what happens when humans panic. If the result is the same, what's the difference?
To put it simply, everyone should have equal access to the market.
HFTers always harp on the liquidity thing. News flash, while liquidity is important, it's not the purpose of the market. Equal access is much more important.
And HFTers absolutely grab profits from everyone else making trades. On the average, HFT makes money. It doesn't make it by finding a customer or building a product, therefore it must come from other traders, Q.E.D.
It's like I'm in the supermarket reaching for an orange and some guy swoops in and buys all the oranges in the store and all the neighboring stores as well and then offers to sell me my orange for a penny more than the prices on shelf. "But," he cries helpfully, "I did you a favor because you can choose from three times as many oranges now!" I just wanted my damn orange for the listed price.
I've got that one, too, and it also is amazing. Precisely *because* it was early great care was taken in it's creation. By the mid 90s almost all CDs were crap. Not because of CDs; because of slapdash work.
You have to expect, though, that in 30 years a bunch of hipsters will be on about how great mp3s were.
Yeah, but back then lots of care was put into making a quality recording for CD because only audiophiles were buying them. Today the care is going into vinyl for the same reason.
Tell you what, you look up the Nyquist-Shannon sampling theorem and then we'll talk.
Few doubt that a quality recording pressed to vinyl is going to be better than slapdash work pressed to CD. There is more to sound reproduction than the medium used to deliver it.
It is? Where does it record the timbre of the particular reed that I am using in my Saxophone?
Take an astronaut to launch.
