Eureka · for Apple Vision Pro · Free
Physics you can pick up and try.
A physics lab that stands on your table. Weigh an object against brass masses, shorten a pendulum and watch its beat quicken, pull a block and feel friction hold on.
How it teaches
A teacher, an instrument, and your own hands.
01
Real instruments, life size
Each one works as the real thing does. The balance tips, the pendulum keeps time, the liquid rises. Nothing is a picture of an experiment: it is the experiment.
02
A teacher who waits
A narrator shows you a part, asks you to touch it or try something, and goes on only when you have. Every course is four lessons: meet, discover, investigate, challenge.
03
Readings that are live
Masses, times, forces and currents are read off as you work. You predict, record results in a table, watch the graph fill in, and the law appears from what you measured.

The shelf
Twenty-one instruments.
Each opens in the browser version, where a mouse stands in for your hands. Sound on: the teacher speaks.
Beam balanceMass is found by comparing it with known masses
PendulumThe period depends on the length of the thread, not on the mass
NewtonmeterWeight is a force: W = m · g
Friction blockFriction depends on the surfaces and on how hard they are pressed together
DiffusionParticles spread out on their own, faster when warm
LeverThe principle of moments: F₁ · d₁ = F₂ · d₂
Measuring cylinderDensity is mass divided by volume: ρ = m / V
Hydraulic pressA liquid passes pressure on: F₁ / A₁ = F₂ / A₂
BarometerThe air presses on everything beneath it
UpthrustA body in a liquid is pushed up by the weight of liquid it displaces
Cart on a railSpeed is distance divided by time
Inclined planeA ramp trades force for distance: the work stays the same
Ray boxLight reflects at the angle it arrives, and bends on entering glass
Specific heat capacityThe energy needed to warm one kilogram by one degree
Resistance of a wireTwice the length, twice the resistance
I–V characteristicsHow current follows potential difference in a resistor, a lamp and a diode
DensityRegular and irregular solids, and a liquid
Force and extensionHooke’s law: F = k · e, up to the limit of proportionality
Trolley and rampNewton’s second law: F = m · a
Ripple tankWave speed is frequency times wavelength
Leslie cubeDull black surfaces radiate more than shiny ones

No headset needed to look.
The browser version has every instrument and every lesson. It works best on a computer. The real thing, on Apple Vision Pro, is the one you pick up.
