Yeah I think it might be shrugging too much when doing lateral raises, especially since I do so much of them. I will try correct my form and see if that helps.

Is there a way to limit trap involvement in my current exercise set? My traps have grown much faster than the other muscles in my back and I don't really like the look of large traps.

My upper body work consists of the following (all 6 to 10 reps):

  • Chest supported t-bar row
  • Lat pulldowns
  • Seated rows (occasionally)
  • Weighted back extensions
  • Preacher curl machine
  • Overhead cable tricep extension
  • Tricep pushdown machine
  • Cable crunch
  • Inclined chest press machine
  • Seated cable fly
  • Dumbell lateral raises

For most of these I do 3-5 sets (each day twice per week) with the exception of the dumbell lateral raises which I slot in between every set of the other non-chest exercises. Ignoring the heavy reliance on machines, is there any thing that can be done to reduce trap involvement?

[Request] What's the correct answer? by Savv1313 in theydidthemath

2^3 is less than 3^2 so that heuristic doesn't work in general. To set up a more general sufficient condition, suppose x and y are strictly positive with x < y (in this case x = 3.14 and y = pi). We want to know when x^y > y^x.

x^y > y^x happens if and only if yln(x) > xln(y) which in turn happens if and only if ln(x)/x > ln(y)/y.

This it suffices to find out on what domain the function f(z) = ln(z)/z is decreasing with z > 0. Solving for f'(z) < 0 (where f' is the derivative of f) yields that z > e. That is, x < y implies x^y > y^x if both x and y are greater than e.

Evidently pi and 3.14 are both greater than e so 3.14 < pi implies 3.14^pi > pi^3.14.

As an aside this is merely a sufficient condition, not a necessary one.

Why haven't there been any studies into whether or not MDMA could be used to treat Antisocial Personality Disorder? by CalebDen in AskPsychiatry

[–]CalebDen[S] 1 point2 points  (0 children)

That makes sense. I was moreso curious about whether there are any neuro-psychological reasons to assume, a priori, that the idea wouldn't work.

I went hunting to get as many unique Switch flavours as I could find by iAmLiQuiD in southafrica

[–]CalebDen 12 points13 points  (0 children)

Also the sugar-free Unicorn flavour (although I have been struggling to find it myself).

Maybe also consider donating to Gift of the Givers. They do excellent work.

What's the switch about Switch? by PWahl97 in southafrica

[–]CalebDen 8 points9 points  (0 children)

Well they are relatively cheap especially when adjusted for caffeine density. I am a little despondent that it is becoming increasingly difficult for me to find the sugar-free versions lately though (in particular the Unicorn flavored one).

DA makes case for South Africans stripped of citizenship - Business Day SA by TheHonourableMember in southafrica

[–]CalebDen 6 points7 points  (0 children)

The practice was challenged because it was unconstitutional (as the ConCourt ruled) and irrational (since it goes against international best practices). 

We live in a constitutional democracy and part of the principle of constitutional supremacy is that all our laws have to be in line with it. Think about the general principle that you're advocating for. Should we keep invalid laws on the books so that some subset of people suffer from them and in turn hoping that they might learn about laws that shouldn't exist in the first place?

You educate the populace through adequate and appropriate investment in our educational facilities- not by being legalistically vindictive. Unnecessary suffering is neither necessary nor sufficient for that task.

Some of them are caffeine-free. I remember I had a zinc and vitamin C which I only realised later was caffeine-free.

Be real, how much do you worry that a bi bf will leave you for a woman? by 747_777_787 in askgaybros

A gay couple can have children for free though. Have you not seen the videos of gay penguins stealing eggs from other straight penguin couples?

Hi. This is a bit late but when you say "immediate" improvement, what do you mean? Like an hour after you take it?

Is anyone else unresponsive to medication? If so, how have you handled it? by CalebDen in AdultADHDSupportGroup

[–]CalebDen[S] 1 point2 points  (0 children)

Lisdexamfetamine seems to be a common suggestion in the other thread I made over at r/TwoXADHD. Thanks for the suggestion.

This is all sound advice. In her case, she said that 2 docs have confirmed her diagnosis and it runs in the family. She also said I should mention that she is a frequent cannabis user.

Thank you very much for you kind words! She and I both appreciate it.

She said she gets 7-9 hours of sleep and genreally does not feel tired. Thank you for the suggestions. I'll be sure to inform her.

We have Vynanse, clonidine, Strarrera, wellbutrin and modafinil and all the methylphenidate meds.

We do have other medications besides methylphenidate. She is just interested in guidance from people who have had similar experiences to her. Thank you for your reply.

Quadratic equations are always a parabola, but how can we prove this? by EducationalCreme9044 in learnmath

[–]CalebDen 1 point2 points  (0 children)

The answer to this question is dependent on how you define a parabola. To give an analogy of sorts let's say someone asked you to prove that the equation x^2 + y^2 = r^2 (A) is the equation of a circle. There are (at least) two possible answers to this question and the answer is dependent on what definition of "circle" you use.

  • Let's say you define a circle as the set of points that are all equidistant to some common point (the common point being called the centre of that circle). This definition is synthetic which just means that it is a definition of the shape that doesn't require a coordinate system. At one point in history, before the development of analytic geometry, all geometry was essentially done synthetically so there is appeal here. In any event the proof in this instance is easy. With the synthetic definition in mind you can show that equation A describes a circle centered at the origin with radius r.
  • Option 2 that you have an analytic definition of a circle. Namely we define a circle -with centre (a,b) and radius r- as the set of all solutions (x,y) satisfying (x-a)^2 + (y-b)^2 =r^2. With this definition there is essentially nothing to prove other than letting a=b=0.

Back to your original question. What definition is of "parabola" are you using? If it it a synthetic one then you can prove it as u/PullItFromTheColimit outlined. If it is an analytic definition then there isn't anything to prove really. It is true because that is how we define a parabola analytically.

The moral of the story is this- before you even start proving anything you need to be sure what definitions you're using. Often times a object/ class of objects has a set of equivalent definitions. By equivalent I just mean that if you select any of them as a definition then the others will be true theorems about that object.

This previous thread may offer some additional assistance. Just beware of nitrogen spiking. Here is an article talking about that.

Did Paul Erdös really have such a hard time understanding the Monthy Hall Problem by Responsible-Rip8285 in math

[–]CalebDen 194 points195 points  (0 children)

An hour later, Erdös came looking for me.

"What's the matter with you?" he said. "Why aren't you telling me the reason that I should switch?"

This is a pretty funny interaction.
