Rough.
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that…

AI not explaining it self… Scary AI… Scary humans…
Upol Ehsan once took a test ride in an Uber self-driving car. Instead of fretting about the empty driver’s seat, anxious passengers were encouraged to watch a “pacifier” screen that showed a car’s-eye view of the road: hazards picked out in orange and red, safe zones in cool blue. For Ehsan, who studies the way…

Measuring… (What?)
A new optical atomic clock makes ultra-precise time measurements. (1) Measuring time. Even though we are not certain what time is. You see, not knowing something does not hinder you from handling it. But this goes even further than that. Not knowing something is the sole pre-requisite of handling it. Because if you knew it,…

Deep learning rethink overcomes major obstacle in AI industry. (So?)
Computer scientists have overcome a major obstacle in the burgeoning artificial intelligence industry by showing it is possible to speed up deep learning technology without specialized acceleration hardware like graphics processing units (GPUs). “The flipside, compared to GPU, is that we require a big memory,” researchers said. (1) We define intelligence with relation to power.…

Limits of measurements… Limits of out self…
The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years. But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg’s uncertainty principle in quantum mechanics implies the presence of “measurement backaction”: the exact knowledge of the location of a particle invariably destroys any…
