NPR Science: Ants That Count!

Desert ants have a nifty way of finding their way back home after a foray out of the nest to find food -- they count their steps. To prove it, some scientists devised a creative experiment that showed just how the little guys do it. NPR's Robert Krulwich and Odd Todd explain. Credit: Robert Krulwich, OddTodd, Jason Orfanon

QBO Robot in front of a mirror ( UPDATED )

Blog Updated with technical info. thecorpora.com This video corresponds to a small experiment in which we put Qbo in front of the mirror to see if he can learn to recognize himself. For that, we used the "Object Recognition" mode and the "Face Recognition" mode. Qbo, using its stereoscopic vision, selects his image in the mirror and, with the help of one of the engineers, learns how to recognize himself. This quite simple experiment touches interesting psychological aspects of self-consciousness, whose complexity can be proved by the fact I already mentioned of the few species that can recognize themselves in front of the mirror. In this first version, a human guide presents Qbo to himself, but we are working so as the robot could present and self-recognize himself autonomously when found in front of the mirror.

Richard Feynman Lecture 4 Part 1/7: Problems in QED and The Standard Model of Particle Physics

Part 2:www.youtube.com In this final lecture of the series Feynman discusses the problems which motivated the development of Quantum Electrodynamics and futher problems in the Standard model of particle physics which includes the Electroweak theory developed by Steven Weinberg, Abdus Salam and Sheldon Glashow which describes the change of particle flavour by means of a type of neutral current which is asymmetric in nature(found in the study of neutrino flavour change in neutrino detectors and the helicity of neutrinos from the polarisation of beta decay experiments found earlier by Chien-Shiung Wu and her colleagues) and in the detection of particles which break the symmetry in electrodynamic and weak interactions, namely the Z-boson wose S matrix matches that of a photon at energies exceeding 100GeV, giving the so-called Electroweak Force. moreover the theory of Nuclear Interactions, in and of themselves, was discovered prior to this, and the interaction of force-carrier particles in the nucleus assumed to exist which explained the missing mass of the atoms and the relativistic properties of the proton and neutron. by detecting high energy cosmic rays and the cascade particles from particle accelerator experiments, a zoo of particles, mesons and baryons was created which were organised in baryon octets and extended into baryon decouplets as new particles were detected with different characteristics which influenced their decay transistions. such decay transitions ...

Make Potassium Permanganate (sort of...)

We make potassium permanganate from the potassium nitrate and manganese dioxide we obtained in previous videos. Warning: This experiment deals with very high temperatures in glass equipment. Face shields and protection against shattering glass is required. In addition small quantities of toxic gases are produced. This experiment should be performed outside or in a fume hood. Make a vial with a mixture of 7 grams of potassium nitrate and 1 gram of manganese dioxide. Using a torch carefully heat the mixture so they melt together. Smoke and fumes should be liberated as the potassium nitrate oxidizes any contaminants in the manganese dioxide. Keep the mixture molten for a few minutes. Now add 2 grams of potassium hydroxide and heat the mixture again thoroughly. It will boil and turn green as the reactants generate potassium manganate. Keep it on a gentle boil for several minutes. Let the vial cool and then smash it apart with a hammer. Obtain the green solid and pulverize it into a powder. Mix this powder with 50 mL of water and dissolve the green potassium manganate. Let it settle and then pour off the solution. The solution can be converted to potassium permanganate by adding drops of either sulfuric acid or sodium bicarbonate. Just keep adding and stirring until the solution turns purple. If you go too far it will turn light pink indicating the permanganate has been destroyed. Let the byproduct of brown manganese dioxide settle out and the liquid is a weak solution of ...
