Physics is OK. I personally hate chemistry.
The big thing in chemistry, is the units! They are always supposed to
cancel out, they say... then why the heck did they invent 80 &*%$ing units
of concentration, mass, etc...
Oh yea chemistry is very concept-based and there are no equations to
memorize, it is straightforward and only requires you to apply some simple
basic skills...
yet in 90% of the problems there are ratios, logs, something that should or
should not be included in the equation, something to add, but not in this
case, because you need to subtract it, because the way the equation is
written is not supposed to be confusing, but it turns out that in this case
it is, because you did not use the correct unit, and they did not cancel
out with the order of magnitude, according to the graph that you didn't
have but you are supposed to know, because for this particular element at
this pressure it is obvious, and you need to know that it always increases going
left to right on the periodic table, except towards the middle, the top
left, the upper left flank, and the bottom right where it goes in the
opposite direction and slightly to the side, because it is overshadowed by
the opposite effect, that only involves liquids, except Helium because it
is a gas, etc, etc, etc... It's always as if they make up the rules as they
go.
And don't even mention organic. O chem is the worst. You have to memorize
10 millions of reactions that only occur in... your textbook, because in
reality it's more complicated, yet we are sure that this bond fits in
between those two because that's the only way they found to explain it in
the book, and it matches the explanation for that other compound, etc,
etc....
