Background: When learning a foreign language, it can be difficult to advance beyond the stage of extremely basic competency. Once a person can “kind of” use a language, it is rare that their communication attempts will be corrected by random strangers, so that person will end up saying things like “Here, there is pancakes served?…

Background: One major concern for any civilization that lasts for more than a few billion years is: what is the best long-term method to reliably store and retrieve energy? Solar panels on a planet work great, but only capture a tiny fraction of total solar output. Some ideas exist for working around this (Figure 1),…

Background: Many people find the relentless piling up of emails in their inbox to be stressful. There are various approaches for dealing with this. The most well-known is probably “inbox zero,” which recommends triaging emails when they’re relatively new (instead of procrastinating and letting them pile up). Although “inbox zero” doesn’t require that you should…

The Issue: When a person is walking around a corner, there’s always a chance that they’ll unluckily collide with someone walking the opposite way (Figure 1). The fundamental problem is obvious enough: there’s just no way to see around the corner. Hospitals and parking garages frequently solve this issue by placing a big convex mirror…

The Issue: Washing machines and clothes dryers save an immense amount of time. But there’s still a significant bottleneck in the pipeline from “dryer” → “pile of clothes” → “dresser / closet”: specifically, the process of actually identifying each article of clothing (Figure 1). Before the pile of clothes can be sorted and put away, the clothes-washing individual will…

Background: Many common household pets have the properties of being soft, furry, and generally snuggleable. These also sound like the properties of a well-designed fuzzy throw pillow, but the pillow lacks at least two sensory properties that a real animal (such as a dog, in this example) can provide: the propensity to lick things, and…

Background: A simple observation: as creatures have become more complex and develop advanced societies, they tend to use fewer limbs for locomotion and more limbs for manipulating the world. Compare these ”civilizational” achievements: Snakes (0 legs, 0 arms): Basically no civilization at all. Dogs (4 legs, 0 arms): Social structures in small groups. No space…

The Issue: Income sources and expenses often operate on mismatched schedules. For example, a person might receive a paycheck every two weeks, but need to pay rent monthly and car insurance every six months. These differing schedules can make it difficult for a person to visualize their cashflow. There are lots of ways to visualize…

Background: In most houses, the process for starting a shower in the morning is as follows: If your shower has separate hot & cold taps: turn the hot tap on first, and wait for the water to get hot. Then, turn on the cold water tap (while avoiding being scalded by the hot water that…

The Issue: Video meetings can be long and boring, and it’s easy for a participant to drift off while a presenter rambles. Unfortunately, the disengaged participant might be suddenly asked a question: they will then need to either reveal that they were spacing out or to provide a feeble excuse to have the question repeated.…
