- The curriculum needs to move away from rote learning to critical thinking to deal with the AI challenge
- Each generation needs to reinvent itself and that cannot be done by mimicking other societies
Subhash Kak, who was recently awarded the Padma Shri for science & engineering-technology, says India needs to move from rote learning to critical thinking. Each generation needs to reinvent itself, says the Regents professor emeritus, Oklahoma State University, US, whose research covers the fields of neural networks, cryptography and quantum computing.
Kak, who has written 20 books, including six books of poems, says what sets humans apart from intelligent machines is awareness, and it is “wrong to assume that consciousness is just a computation”.
“My research has led me through various pathways, some of which touch on ancient wisdoms and others on modern science,” writes Kak, who is also a Vedic scholar, in his book The Circle Of Memory: An Autobiography (2016).

- Researchers discover a method of extracting previously unavailable information from superconductors.
- The study builds on a 19th-century discovery by physicist Edward Hall.
- The research promises to lead to a new generation of semiconductor materials and devices.
New research, led by IBM, made a breakthrough in resolving a mystery that has baffled physicists for 140 years. It promises to lead to a new generation of semiconductor materials and devices that use them.
- Philosopher Nick Bostrom argues that humans are likely computer simulations in the “Simulation Hypothesis”.
- Bostrom thinks advanced civilizations of posthumans will have technology to simulate their ancestors.
- Elon Musk and others support this idea.
Cientistas fizeram registro sem querer. Fenômeno microscópico ocorre em escala 500 mil vezes menor que a espessura de um fio de cabelo
Pela primeira vez na história, cientistas da Universidade de Nottingham, na Inglaterra, filmaram átomos rompendo e formando ligações químicas. O fenômeno microscópico ocorre em uma escala muito pequena, entre 0,1 e 0,3 nanômentro — o que é 500 mil vezes menor que a espessura de um fio de cabelo.
We know that the realm of quantum physics is science operating at a mind-bogglingly small scale, thus watching quantum interactions happen is always exciting. Now, physicists have managed to observe billions upon billions of entangled electrons passing through a metal film.
The film is a mix of ytterbium, rhodium and silicon, and is what’s known as a ‘strange metal’, one that doesn’t act as expected at very low temperatures.
“With strange metals, there is an unusual connection between electrical resistance and temperature,” explained physicist Silke Bühler-Paschen from Vienna University of Technology in Austria.
“In contrast to simple metals such as copper or gold, this does not seem to be due to the thermal movement of the atoms, but to quantum fluctuations at the absolute zero temperature.”
These fluctuations represent a quantum criticality – that point between quantum states which are the equivalent of transition between liquids, solids and gases in classical physics; the team says this cascade of electrons is the best evidence yet of a link between quantum criticality and entanglement.
