Watch any Ted Talk and you get some model of public speaking, a way how to approach, attract and attain the attention of the audience. Most of the speakers are actually good speakers and combined with expertise or experience with their topic, Ted Talks are one of the best form of non-formal education. I even used them at school with children. Nevertheless, here are five talks that made the biggest impact on me.
1, Amy Cuddy: Your body language shapes who you are
Many people still need to find out that we actually communicate even if we turn back to the people. Non-verbal communication covers over 60 percent of communication. Our body posture reflects our feelings and emotions, communicates the status. Standing firm with head up we start to feel confident; hunched over a phone makes us feel shy. Faking the body-pose can really influence how we feel.
2, Helen Fisher: The Brain in Love
Why we want what we will never have. Romantic love is associated with the subconscious part of the brain, responsible for wanting, motivation, focus and passion. These cells that also make dopamine and are associated with cocaine high. Similarly, we are obsessed with the person. Obsession gets worse when we get rejected, like having abstinence symptoms.
Here we find out why someone keeps trying hard and never achieve the top and someone just comes and wins. How genetics and biomarkers influence performance and even the appearance of people.
4, Meg Jay: Why 30 is not the new 20
There is nothing bad on waiting with commitments till 30 provided that we spend the years effectively. Moreover, should not break old commitments just in order to experience something new. Meg warns that there is sometimes very thin line between looking for a new experience and procrastination.
5, Scott Fraser: Why Eyewitnesses get it wrong
Forensic expert explains why we see what we want to see and how our brain affects perception of what really happened. A tiny picture that comes through our retina gets distorted in a much bigger surface of cells. We apply our experience and knowledge and this alters the real picture.

Clio is a Senior Lecturer in Mathematics at The University of Sydney, researching evolutionary mathematics. She starts with equation and gives history brief on how is mathematics the basic element of all sciences (my colleague – physics teacher – used to say that mathematics is the basics of physics). In the 19th century, mathematics started to be used in economic predictions and it is also involved in relationships and sex.
Finally, a talk on relationships from a woman who takes it from the supply-side point of view, not from the psychology and compassion. !!!
Mark Bittman is a food journalist and former columnist for The New York Times.
LOCAVORE is someone who eats only locally grown food. Hundred years ago everyone was a locavore – margarine was banned and there were no fast foods, no food brands, no vitamin products. Food was food. From the 1930’s, transport option expanded and food has become an industry. Preservatives are added in order to expand the shell life and the food has lost the original taste and properties. It can be even the source of allergies and diseases. We must take the responsibility into our hands and do not rely on the products sold under the label ‘food’.
American economist whose writings (together with Stephen Dubner) helped me to see how the world works, while I worked in a hotel in London.
Why drug dealers live with their mother? Because their job on the lowest level is dangerous and does not earn much.
Levitt’s colleague infiltrated into a Chicago gang and lived with them for three months. Real terrain research of how economy works… A gang is organized into a hierarchy like a McDonalds restaurant. The ordinary staff comes and goes every day and only the guys at the top earn a decent living. For the ordinary drug sellers there is a 25 percent probability to be killed, even higher than soldiers in Iraq.
Compensating differential = compensation for high risk or other aspects related to the nature of job. The gang members are paid
