The Best Free Data Science Courses on the Internet

Data science is blossoming as a field at the moment. Popular jargon from traditional statistics to new machine learning techniques are used colloquially in both online articles and day-to-day exchanges. One of the excellent things about data science, noted by David Venturi, is that by nature the field is computer-based. Why not learn about it all for free online then? Venturi has written several articles enumerating lists of massive open online courses (MOOC) relevant to someone interested in only a single highly-ranked data science class, or a complete masters degree in data science for the more dedicated individual. One of the benefits of these courses is they are more poignant and focus on only the knowledge relevant to applying data science skills. Another perk is the nonexistent price tag, as opposed to the tens or hundreds of thousands of dollars of student loans one could thrust themselves into while pursuing a data science masters at a formal institution. Venturi explains why he left grad school to learn about data science before finishing his first semester. If nothing else, some of these courses may be useful to supplement a graduate school education.

Stomach Vacuum Exercise

How to Perform Stomach Vacuum

  1. Stand upright and place hands on hips or behind neck
  2. Exhale all air from lungs completely
  3. Expand chest, bringing stomach in as much as possible
  4. Hold for X seconds (visualize touching naval to lumbar spine)
  5. Bonus: flex groin muscles (as if stopping flow of urine)

Training Guide

3 days each week:

  • Week 1: 3 sets of 20 seconds
  • Week 2: 3 sets of 40 seconds
  • Week 3: 3 sets of 60 seconds

Alternative positions

Lying prone, kneeling, seated

Transversus Abdominis and Multifidus Muscles

Stomach vacuuming strengthens transversus abdominis and multifidus muscles.

Strengthening transversus abdominis (TrA) and multifidus muscles has been reported as a treatment for lower back pain. However, a systematic review was inconclusive and provided mixed results; strengthening these muscles may prevent back pain, but a strong statement for or against this causal relationship cannot be made without better evidence. Ideally large, prospective studies would be used to investigate the association of TrA and multifidus strengthening exercises with reduced lower back pain.

Importance of Stupidity in Science

The Importance of Stupidity in Scientific Research

“Science makes me feel stupid too. It’s just that I’ve gotten used to it. So used to it, in fact, that I actively seek out new opportunities to feel stupid. I wouldn’t know what to do without that feeling. I even think it’s supposed to be this way.”

The more comfortable we become with being stupid, the deeper we will wade into the unknown and the more likely we are to make big discoveries.

“Productive stupidity means being ignorant by choice. Focusing on important questions puts us in the awkward position of being ignorant. One of the beautiful things about science is that it allows us to bumble along, getting it wrong time after time, and feel perfectly fine as long as we learn something each time. No doubt, this can be difficult for students who are accustomed to getting the answers right. No doubt, reasonable levels of confidence and emotional resilience help, but I think scientific education might do more to ease what is a very big transition: from learning what other people once discovered to making your own discoveries. The more comfortable we become with being stupid, the deeper we will wade into the unknown and the more likely we are to make big discoveries.”
