In India we have heard about Rishi’s who used to sit under a tree and meditate for…

There are other factors too, such as regulations which make it illegal to sell un-pasteurized milk, horse meat, foie gras, etc., but the biggest factor influencing what the average American eats is the margin the grocery store makes on the products it sells. This explains why you can't get redcurrants or passion fruits anymore, but you'll find plenty of high energy drinks and food rich in sugar…

Job titles for data scientists

I looked at the job titles of my 7,500 LinkedIn connections, and found about 4,900 unique job titles. The vast majority of my connections work in data science or some analytic field. Some very popular job titles do not contain an analytic keyword: for instance CEO, Consultant, Founder.
