Some movies do time travel right. Other movies do time travel wrong.
This is not an artistic assessment. It’s a metaphysical truth, at least according to philosophers. Regardless of whether time travel will ever be physically possible, the question we’re going to consider is how it would work logically if it did work at all. Here we explain the philosophical quandaries that mean The Terminator and Harry Potter make a certain kind of sense, while Back to the Future doesn’t quite hold up to scrutiny.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
