Counting till the end… Numbers… Infinite… Water and fire…
Gisin, of the University of Geneva, debates the physical reality of real numbers. His main problem lies with real numbers that consist of a never-ending string of digits with no discernable pattern and that can’t be calculated by a computer. Such numbers (like π for example) contain an infinite amount of information: You could imagine […]

Engraved symbols. Long gone. Deep into our heart…
Engraved stone artifacts are important clues to the history of human culture and cognition. Incisions on the cortex (soft outer layer) of flint or chert flakes are known from Middle and Lower Paleolithic sites across Europe and the Middle East. However, it can be difficult to determine the action that created an incision: was it […]

Brain waves. A calm lake…
Our brains hum with electrical activity. Brain waves created by the coordinated firing of huge collections of nerve cells pinball around the brain. The waves can ricochet from the front of the brain to the back, or from deep structures all the way to the scalp and then back again. Called neuronal oscillations, these signals […]

Brain. One with the body. Falling in love.
At a small eatery in Seville, Spain, Alan Jasanoff had his first experience with brains — wrapped in eggs and served with potatoes. At the time, he was more interested in finding a good, affordable meal than contemplating the sheer awesomeness of the organ he was eating. Years later, Jasanoff began studying the brain as […]

From electrons to photons. From photons to electrons…
The quantum computer of the future will be able to carry out computations far beyond the capacity of today’s computers. Quantum superpositions and entanglement of quantum bits (qubits) make it possible to perform parallel computations. Making useful computations requires large numbers of qubits and it is this upscaling to large numbers that is providing a […]
