PBS Space Time explains how general relativity permits warp drive in principle and covers recent theoretical advances toward solving the negative energy problem.

WeberAuto explains how the Honda E-Drive (i-MMD) hybrid transaxle works in the CR-V, Accord, Insight and Clarity hybrids. It walks through the system's three modes of operation.

Not Just Bikes argues that the Netherlands, famed for cycling, is also the best country for drivers. It explains how prioritizing walking, cycling and transit makes driving faster and more pleasant.

A short urbanism video presenting original observations of how drivers treat stop signs, to argue that cyclists rolling through them under an Idaho stop is no different. It filmed intersections in Ottawa.

Tom Scott visits the Swiss Military Museum to see the last surviving 1970s tank-driving simulator. It uses a real camera moving over a miniature model landscape rather than any computer graphics.

A Vox explainer on why California's high-speed rail project is years late and far over budget, with only a few concrete structures built by 2022. It covers the political, legal and routing challenges behind the delays.

A nutrition-science explainer reviewing the human evidence on whether seed oils cause inflammation. It looks at nine different seed oils, heated oils, and genetic variability, and compares omega-6 intake with saturated fat.

Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.

A What I've Learned video arguing that industrial seed and vegetable oils have displaced saturated fats and harmed health. It covers the history of vegetable oils, the American Heart Association's role, and rising consumption.

CityNerd explains why traffic congestion grows nonlinearly as more cars use a road network, and why adding road capacity tends not to fix it. It covers the consequences for drivers, bus riders, cyclists and pedestrians, and discusses alternatives such as true bus rapid transit.

Veritasium examines the role of luck in success, with simulations and examples showing how small advantages and chance can compound. It argues that top outcomes are disproportionately luck-driven while still crediting effort.

Everyday Astronaut's Tim Dodd runs an hour-long, data-driven analysis of what rockets actually emit and how that compares with airliners and other industries. It breaks down exhaust by propellant type, per-passenger and total emissions, and ways launches could be cleaner.

RealLifeLore explains with maps why Russia invaded Ukraine, focusing on energy resources, security buffers, Black Sea access and Crimea's strategic value.

Veritasium tells the history of how imaginary numbers arose from the quest for a general solution to the cubic equation, including the duels and secrecy among Renaissance mathematicians. It argues math had to give up the requirement that it mirror reality.

Technology Connections' hour-long guide to electric vehicles, covering costs, trade-offs and especially how little home charging power most drivers need.

A Vox explainer on how the wildlife trade and wet markets are linked to coronavirus and why new diseases keep emerging in China. It stresses that most people in China do not eat wildlife.

Tom Scott makes the difference between a million and a billion dollars tangible by using distance on a road trip instead of volume. The drive makes the scale of a billion intuitively felt.

Tom Scott explains why Ipley Cross in England's New Forest was one of Britain's most dangerous junctions. The angled crossroads lets a car's A-pillar hide approaching traffic and cyclists because there is no relative motion in the driver's view.

An episode of Plogue's chipresearch series on emulating the Yamaha DX7 from the hardware up. It covers the sub CPU and main CPU, address map investigation, cartridges, firmware analysis and a skeleton MAME driver.

A Kurzgesagt animated explainer on the climate and environmental cost of meat. It covers how beef drives deforestation and emissions, and how this compares with plant-based foods.

Dr. K of HealthyGamerGG explains why people feel unmotivated and unable to start tasks after hours of YouTube or similar distractions. He frames it as a result of how social media is designed to capture attention, and says not to blame yourself.

Yosh trains a reinforcement learning agent to drive Trackmania until he can no longer beat it. The video explains how the training works and the design choices involved.

A Wendover Productions video on how the art market works, arguing that prices are driven by wealth, storage and tax mechanics rather than artistic value.

Autoline's John McElroy and Caresoft president Terry Woychowski look at the BYD Seagull, an electric hatchback that sells in China for about $11,500. Woychowski points out the cost-saving design and manufacturing choices, and McElroy takes it for a short test drive.

A short animated explanation of the power split device in Toyota-style hybrids, a planetary gearset that works as an eCVT. It shows how engine and motor power are combined.

Not Just Bikes looks at traffic in the Bahamas to show that a small country can be just as car-centric as a big one. He ties it to land use, car dependence and how dedicated transit lanes help.

A 3D-animated walkthrough of a heavy-haul diesel-electric freight locomotive, covering the frame, coupling, draft gear, engine and drive systems. Made in Blender by Animagraffs.

CityNerd's Ray Delahanty tallies the personal costs of driving and then the externalities that car dependency imposes on everyone else, with numbers for each. It is an urbanist case that driving is heavily subsidized and costs society far more than drivers pay.
