    • Facts. Evidence. Reason. Logic. An understanding of science,” Mr. Obama said. “These are good things. These are qualities you want in people making policy. These are qualities you want to continue to cultivate in yourselves as citizens.”
    • So class of 2016, let me be as clear as I can be: in politics and in life, ignorance is not a virtue. It’s not cool to not know what you’re talking about. That’s not keeping it real or telling it like it is. That’s not challenging political correctness, that’s just not knowing what you’re talking about. And yet we’ve become confused about this.”

    • Okcupid is a big reason I got into data science! I think they’ve shared some fascinating insights over the years.


      If anyone wants to replace the question keys in user_data.csv with the text from question_data.csv, you can use this Python script. Maybe it’s obvious, but I struggled with it for a bit so I thought I’d share it.


      f_data = open('user_data.csv') reader = csv.reader(f_data) data_csv = [line for line in reader]  f_questions = open('question_data.csv', encoding='utf-8') reader2 = csv.reader(f_questions, delimiter=';') questions_csv = [line for line in reader2]  for i in range(len(data_csv[0])):     for row in questions_csv:         if data_csv[0][i] == row[0]:             data_csv[0][i] = row[1]
    • A 1:59:59 marathon would require a searing pace of 4 minutes 34 seconds per mile, seven seconds faster than the pace of the current world record. It would require 85 to 90 percent of a runner’s maximum aerobic capacity — twice the capacity of an average man — and a sustained heart rate of about 160 to 170 beats per minute. (The typical resting rate is 60 to 100 beats per minute.)
    • Michael Joyner, a researcher at the Mayo Clinic, predicted in 1991 that it was possible to finish in 1:57:58. But numerous experts predicted that two hours would not be breached until 2028 or 2035 or even 2041.
    • Many elite marathoners, for instance, run about 120 miles a week in training. But there was little science to support that regimen, Pitsiladis said. Perhaps 75 miles a week would work just as well for many runners — or maybe any reasonable training program would.
    • Live high, train low is supported by some evidence. But Pitsiladis is not fully convinced of its efficacy, saying, “I would bet you it’s wrong and that what’s better is live high and train higher,” as perhaps the two greatest distance runners in history — Haile Gebrselassie and Kenenisa Bekele of Ethiopia — often did.
    • As a doctoral student, Pitsiladis experimented with giving runners a pint of heavy cream as a prerace meal. The idea was to use fat and help delay the depletion of carbohydrates, the body’s main fuel source during high-intensity exercise.
    • But Pitsiladis had come to believe that a two-hour marathon might be best achieved by bombarding the system with glucose.
    • For instance, Owen Anderson, a consultant to the Sub2 Project who coached elite Kenyan road runners in Michigan, gave his athletes eight to 10 ounces of a sports drink about 10 minutes before a race to get accustomed to a bloated feeling. (They drank more during competition.) To further get accustomed to an uncomfortable feeling in the stomach, the runners sometimes practiced by eating ugali, a Kenyan porridge, or cabbage before training.
      • Good idea – but you really just need sugar water
    • Against convention, Pitsiladis theorized that the second half of a two-hour marathon would be run faster, not slower, than the first half. As runners burn fuel and become lighter during a race, he said, they should become more economical, needing less oxygen to maintain a certain speed.
    • When runners drank, Pitsiladis believed, they could shave precious seconds by squeezing fluid from a bag instead of opening a bottle, as elite runners do on the course. And perhaps, he said, they needed to drink little or nothing in the second half of a two-hour marathon.
      • bag idea is ok.
    • Instead, they might rinse their mouths with a carbohydrate solution and spit it out. Research showed the brain could be tricked into believing that more carbs were on the way, thus inducing the muscles to work harder.
    • Lamine Diack of Senegal, a former president of track’s world governing body, is accused of having taken more than $1 million in bribes to cover up positive drug tests by Russian athletes. He remains under investigation by the French authorities.
    • East Africans already receive top coaching and scientific advice and have decades of experience and huge economic incentives to inspire their performances, Tucker wrote on when the Sub2 Project began. These runners, he wrote, “laugh at Westerners for their heart rate monitors and gadgets because they understand their bodies so well already.”
    • But he also considers the dominance of Kenyan and Ethiopian distance running to be largely due to cultural and socioeconomic factors. In other words, he said, genes need the proper environment to thrive.

      At his TEDx talk in Cyprus, Pitsiladis described a study of his that found Kenyan children engaged in 170 minutes of moderate to vigorous activity a day, compared with 20 to 40 minutes for Europeans.

    • “The president’s role will be strategic and ambassadorial and no longer executive,” they wrote, directly stating that the kind of centralized authority figure that typified Sepp Blatter’s time was dead. In its place would be a ceremonial role, where the actual work of operating a billion-dollar business would be left to the background staff.
    • FIFA’s secretary general, under the position’s disgraced former title-holder Jérôme Valcke, has been a very prominent, business-oriented job.
    • By hiring Samoura—again, someone who has spent the last 20 years at the UN, not in the business world—there is an open question as to who will take the reigns on things like broadcasting rights contracts.
    • This is believed to be the clause that led longtime reformer and FIFA audit and compliance chairman Domenico Scala to walk out of the Congress.
    • No. His name is Wishbone. Unlike his human companion, Wishbone is a great lover of books. When Joe’s life reminds him of a masterpiece, as it so often does, our canine Virgil guides the audience on a journey into that book.
    • SUIT #1: Ah, I get it. In the book part, all the characters are played by dogs?

      VISIONARY: You get nothing. Wishbone plays a character, for example Romeo in Romeo and Juliet, and the other parts are played by adult human actors.

    • SUIT #2: Like they just never acknowledge he’s a dog?

      VISIONARY: I mean he wears a costume, so.

    • SUIT #3: Literally Wishbone is wearing a Romeo costume and standing in front of a grown woman in an Elizabethan gown who’s asking him to deny thy father and refuse thy name, but no mention of the fact he’s a dog?
    • SUIT #2: And the dog-teaching-kids-to-read concept, that’s perfect for our demographic.

      VISIONARY: He doesn’t teach them to read. He inculcates in them a passion for timeless narratives.
