<p>Definitely agreed!<p>When I started my Ph.D. program, there was a weekly seminar that I started going to. At first, I instinctively left each week immediately after the talk was over. But I noticed that a lot of people would hang around afterwards and chat. Even though I found it a bit awkward, I started following their lead -- a habit I'm very glad I developed!</p>

<p>Personally, I've enjoyed classes in yoga and in group fitness.<p>This has several advantages: exercise is obviously good for you, and you can meet people while you're there. But more subtly, once you show up, someone is constantly telling you what to do. For me, this has meant much less of a drain on my mental energy and discipline than if I tried to work out on my own.<p>Good luck!</p>

<p>Yes, they likely scraped the conference web site.<p>Academia, at least in math, has a tradition of being public. Conferences will advertise at least the list of speakers, and sometimes the full list of attendees. This is widely considered a good thing; people trying to decide whether to go to a conference will want to know who else will be there.<p>Moreover, the conference organizers have sent out multiple emails to the attendees warning that scammers were targeting them, and emphasizing that there were no third parties legitimately involved.<p>So I can't and don't fault them.</p>

<p>A scammer just attempted to phish several attendees at a scientific conference. They falsely claimed to be affiliated with the conference, and asked for their credit card numbers.<p>The request was made via a document signing service which is apparently legitimate. The email came from the signing service's domain.<p>I got in touch with their customer service, and they refused to claim any responsibility: "We do not take responsibility for the actions or communications of companies that choose to use our service. If the email you received originated from an external organization, any concerns about its content or legitimacy should be addressed directly with that organization, as the document's sender and owner."<p>Obviously I am not going to correspond with a scammer for any reason.<p>Is this legal?? Do I just need to accept that this is the world we live in?</p>

<p>I got curious, and looked up the Harvard Polo Club. Apparently it naturally faded away as polo declined in popularity, but then was revived in 2006.<p>I understand that, if you have a current and active polo club running, then you either have to keep it going or run the risk of pissing people off.<p>But, if I can ask you to speculate, why might Harvard have revived its club in 2006?</p>

<p>I certainly didn't take it as a slight against myself. Rather, I've met Tao and several other top mathematicians, and I don't imagine any of them would say they fit that description.<p>Indeed, Tao himself has written criticism of the "cult of genius":<p><a href="https://terrytao.wordpress.com/career-advice/does-one-have-to-be-a-genius-to-do-maths/" rel="nofollow">https://terrytao.wordpress.com/career-advice/does-one-have-t...</a></p>

<p>I'm a research mathematician working in Tao's field. I'm not claiming to be as prolific as he is, not by a long shot -- but other mathematicians <i>do</i> understand, critique, develop, and engage with his work. Indeed, many of his papers are collaborative with a variety of other mathematicians.<p>Picture him as the star player on a basketball team. He may be the strongest player on the court, but he's still playing the same game as everyone around him.</p>

<p>If people are scared to share their thoughts, then <i>that</i> seems like the problem.<p>Also, how much of this communication is actually necessary? If someone doesn't care about an issue enough to write their own email, then why are they sending an email about it in the first place?</p>

<p>I'm a professional mathematician and professor.<p>This is a very interesting question, and a great motivator for Galois theory, kind of like a Zen koan. (e.g. "What is the sound of one hand clapping?")<p>But the question is inherently imprecise. As soon as you make a precise question out of it, that question can be answered trivially.</p>

<p>Agreed. On my phone I turned off most of my notifications, and on my computer I turned off <i>all</i> of them.<p>I couldn't find any way to actually turn off notifications in MacOS. But you can set "quiet hours" to be from 2:00 AM until 1:59 AM.</p>

<p>I haven't, but others have written about the same trip. There's lots of material online these days, I'm not really familiar with it but if you google "Shikoku henro pilgrimage", all the hits will be about the same trip I took.<p>There is a wonderful book, <i>Japanese Pilgrimage</i> by Oliver Statler. He goes into the history of the pilgrimage and of Kobo Daishi, the monk whose path the trail follows. He also discusses his own personal experience walking the trail.</p>

<p>A variant of this advice, that avoids some of the pitfalls, is to take time off to do something structured and specific.<p>Personally, in between jobs a long time ago, I chose to walk the Henro Trail, an approximately 800-mile Buddhist pilgrimage trail in Shikoku, Japan. To make a long story short, it was the experience of a lifetime.</p>

<p>> Are you an expert?<p>I can't speak for ndriscoll, but I am a university math professor with extensive experience teaching these sorts of topics, and I agree with their comment in full.<p>You are right that some (other) statements are harder to formalize than they look. The Four Color Theorem from graph theory is an example. Generally speaking, discrete math, inequalities, for all/there exists, etc. are all easy to formalize. Anything involving geometry or topology is liable to be harder. For example, the Jordan curve theorem states that "any plane simple closed curve divides the plane into two regions, the interior and the exterior". As anyone who has slogged through an intro topology book knows, statements like this take more work to make precise (and still more to prove).</p>

<p>If the government's guidance isn't to be at least mostly trusted, then I'm not sure the government should be offering guidance at all. (Which is perhaps a sensible position in itself.)<p>In other words, if I learn enough about nutrition to be able to critically evaluate the government's guidance, then is that guidance adding any additional signal? At that point, I should just rely on my sources about nutrition.<p>I've never been one to rely on official guidance blindly. For example I don't show up to the airport two hours early, and cheerfully laugh at advice that I should. But I'd like to believe that this guidance is better than total nonsense.</p>

<p>This could certainly be fantastic, and very good advice. Or it could be a lot of bunk, I don't know. Given the source (i.e., RFK), I refuse to trust it.<p>The point of guidance like this is to be trustworthy and authoritative. If I have the ability to independently evaluate it myself, then I didn't really need it in the first place.<p>Of course, I might be mistaken to have <i>ever</i> trusted the government's nutrition guidance. It's not like undue influence from industry lobbying is unique to this administration.</p>
