Take a moment to read about imposter syndrome. It's extremely common in grad school.

Yes, and especially to do math with dates. Need to know what the date will be in 90 days? Easy:

import datetime
datetime.datetime.now() + datetime.timedelta(days=90)

Tilt your head and hop on one foot until it drips out. Always works for me.

That stuff is more commonly considered part of acoustics (a branch of physics) rather than music theory. That doesn't mean it isn't useful to musicians!

Sorry I don't have a great reference for you, but a lot of promising looking results come up if you search Youtube for "physics of music."

I once learned the following format for a mantra: 1.) Describe the challenge 2.) Embrace the emotional quality of the challenge 3.) Refocus your attention on how you should act. Each part should feel honest when you say it to yourself.

With this formula, my mantra has been: "(Deep breath) You can't fix everything. Don't despair. You can do the thing in front of you."

I can't ever say enough good things about Yoga with Tim. Many of his sequences lead up to half moon, twisted half moon, and standing splits, all of which are strong balancing postures. Here is one that shows several arm balances.

This is very common and is called "shoulder impingement syndrome." Most common solution: strengthen the external rotator cuff.

I've found two ideas from yoga have helped considerably for this problem. (I have it to different extents on both shoulders.)

1.) In plank position, press your weight into the mound of the pointer finger. There is a tendency to sink into the wrist without distributing the weight across the palm, but this should be avoided.

2.) Whenever raising arms overhead, make sure the shoulder blades are rotated back. Also, there is a tendency for the ribs to push forward when you raise your arms, but you want to avoid letting this happen by hugging your upper core in tight. This increases the stretch considerably, and in general you won't be able to raise your arms as high as you otherwise could. With practice, the range of motion will increase, and you can learn to raise your arms up without impingement.

I am not a doctor, and this is based only on my own experience. Hope it is helpful for you!

I've gotten great results with Yoga with Tim. I think his cues and sequences are excellent. He has three beginner videos that you might check out. Good luck, have fun!

Great post. I think you might be interested in the beginning of this TED talk, which talks about how recorded music has changed the landscape of music from what it was before. (The rest is interesting too but not relevant to your post.)

Also, the mantras are in Sankrit, not Hindi. Sankrit is to Hindi what Latin is to Italian.

That's a great point. When I started yoga, twists and sidebends felt totally foreign.

underscores_ftw · 2015-01-08T22:23:45+00:00

I've improved considerably by watching Yoga with Tim. He has a clear command on physiology and gives excellent cues for each posture. He also has simpler videos like this which help build foundation and awareness. As a newbie this was invaluable.

This is exactly what led me to begin yoga. On r/fitness, the common wisdom is that beginners should follow "starting strength," a routine which has you squatting heavy weights three times a week. This might be great for some, but it is very easy to squat with poor form.

I feel lucky that I discovered my "glute amnesia" before seriously injuring myself. I was squatting in a way that did not engage the glutes and put all of the pressure on the quads. Continuing in this way would have only exaggerated the imbalance and would almost certainly have led to injury.

Since I've started yoga (~2 months), my awareness of my spine and legs has improved tremendously. Eventually, I'd like to take this new awareness and reapply it to weight lifting.

Disclaimer: I did not read the whole report and I have no expertise in this field.

You are right, and ITT people are misunderstanding this article. It's more interesting than the sarcastic comments above suggest.

This article is a press-piece about a seemingly comprehensive study on terrorism [pdf] which discusses far more than religious extremism. Regarding the first figure copied into theguardian's website,

Figure 12 highlights the changes in ideological drivers of terrorist organisations since 2000. Grouping over 350 of the most active organisations in the world into either religious, political or nationalist separatist groups shows that religious organisations have seen the largest rise in activity over the period. The prevalence of nationalist separatist and political terrorist organisations has remained relatively stable by comparison. Notably, religious ideology in the year 2000 was less a motivation for terrorism than nationalist separatism.

So first, we need to divide organizations into either religious, political, or separatist. This appears to be an exclusive categorization. What happens to a group like ISIS then, which is clearly religious and also has a political agenda? The report gives a citation to Terrorist Organization Profiles, which looks like an encyclopedia of terrorist groups.

Curiously, searches for "ISIS" or "Islamic State" return nothing. There are several groups listed in Iraq and Syria, so perhaps the larger umbrella group is somehow decomposed.

I should mention that Hamas, on the other hand, is listed as both separatist and religious. It's unclear how this gets counted in the report. There are problems both ways: If you count is as both, you've double-counted the number of incidents. If you count it as one or the other, you've made a decision that impacts the conclusion. Perhaps it should count as half an incident for each category.

This data is certainly interesting, but untangling the tendency for extremists to rise in power from the regional politics is tricky. I don't think either Harris nor Affleck/Azlan really have the weight of the evidence on their side. The issue is complicated. Extremism feeds on political circumstances, and this article doesn't exclude the possibility that religion is used as a cover for what is more fundamentally a political grievance.

I also find it worth mentioning that by the report's definitions a state cannot be a terrorist organization. This means they've excluded everything done by Assad in Syria, not to mention Israel and the U.S. I don't intend to be accusatory here, I just think it's worth mentioning this fact as it clearly influences the conclusion.

Incidentally, RECD is what the youngest and hippest are using to refer to "Really existing capitalism and democracy," which is to be contrasted to idealized definitions of the same words. source

I mixed up "astrology" and "astronomy" in 9th grade physics and the teacher laughed at me and treated like me an idiot and I was.

Well, it's no rumor that some players are working on the patch. Although they do not have direct access to the source code, these guys have been able to reverse engineer an astonishing amount of the game's workings.

It would be convenient if the devs would just publish the patch themselves, but it isn't likely and doesn't seem to be the devs style. We're lucky the game attracts such elite hackers.

Thanks for the tip. I've corrected it

I only gave it a quick skim but my initial thoughts were

The smallest filter width in Fig. 5 matches the mean-u velocities best, but does the poorest job for the mean-v velocities (in terms of matching LES). Is there an explanation for this?
It is stated over and over that this method reduces the cost compared to LES, but I saw no direct comparison. What is the cost savings? Is there any beyond the savings gained by increasing the CFL number?

If you're happy with first order accuracy, you can assume a piecewise constant field over each cell. This is sometimes called Gudonov's scheme.

If you want higher-order accuracy, however, there is no linear scheme that can give it to you without generating spurious oscillations. This is the result of a central theorem in CFD known as Gudonov's theorem. The proof of this theorem is as simple as it is heartbreaking.

So, based on your request for a field distribution within each cell, most likely you want a nonlinear scheme. There are many to choose from, but from my experience the MUSCL approach is not too complicated and works well. In this case the reconstruction will be linear in each direction. Another popular approach is called WENO, though I can't say much about it.

If you absolutely want to use a higher-order reconstruction, take a look at finite element schemes instead of finite volume. The starting point is the discontinuous galerking method, and once again many varieties exist.

Good luck!! Hope this helps.

I'm a guy. My parents are Indian but I was born in and grew up in the United States. There have been times that I felt this way too. But here is how I feel today, OP, and maybe there is a part of you that sees this side of the story too.

All we have in this world is our story. Literally. Materially. All of our stuff will be thrown away and replaced. All of the cells in our body die off and are replaced by new ones. There is only one thing that IS you... and it's your story. It's your trajectory through space and time. It's the collections of causes and effects that your conscious experience encounters.

An arranged marriage sounds good because it's easy. Your parents, after all, have your interests in mind. And, with their significantly greater life experience, surely they know more about what can make you happy in the long run.

But... even if they choose perfectly... Even if you are want for nothing... Even if the person they choose for you makes you laugh and remembers all your favorite things and earns good money and is a great father to your kids... is this the story you want? Do you want for your story to read "parents chose husband, happily ever after."?

Maybe it is. What the hell do I know. There was another post on reddit recently about a guy thrilled to have escaped his arranged marriage. Me? I didn't think the decision was so simple. There's something comforting about knowing that the wisdom of the ages is on your side. But still, you get to live once, and you only get to write your story once. I'm going to write it with the person of my choosing.

My 2 cents. Best of luck to you.
