What is a neuronal avalanche?
Neuronal avalanches are cascades of propagating activity that follow power laws and are a hallmark of criticality. They are contiguous cascades of spiking activity, rather than limited local bursts of spiking activity or huge network-wide spiking events. The start and stop of an avalanche are determ...
ViewWhy does popcorn pop, and why do some kernels stay unpopped?. Break down the role of moisture, pressure buildup inside the hull, starch gelatinization, and the explosive phase change that flips the kernel inside out. Cover common reasons for duds like cracks, low moisture, uneven heating, and old kernels.
Popcorn pops because each kernel contains a specific amount of water, ideally around 14%, trapped inside a tough outer shell called the pericarp. As the kernel heats above 180°C, this water turns into pressurized steam, transforming the internal starch into a hot, gelatinous material. Eventually, th...

ViewHow do traffic lights detect cars and coordinate timing across a city?. Break down the sensors (loops, cameras, radar), then explain the difference between fixed-time schedules and adaptive control. Close with how coordination creates green waves and why it sometimes fails during unusual traffic patterns.
Traffic lights are not guessing. They can detect cars with buried loops, cameras, radar, infrared, and even connected-vehicle data, then feed that info into a controller that decides what gets green next. The classic sensor is the inductive loop: a wire coil cut into the road that watches inductance...

ViewFive fast facts about supercapacitors and why they charge so quickly. Create five punchy cards covering how energy is stored (electric double layer and pseudocapacitance), power versus energy tradeoffs, cycle life, typical voltages, and real-world uses. Keep each card surprising and practical, contrasting them with batteries in plain language.
They store energy physically by lining up ions on electrode surfaces rather than using slow chemical reactions. Supercapacitors can deliver massive power bursts instantly, while batteries are better for long-term, steady energy output. They can handle over a million charge cycles, lasting far longer...
