Christmas Lecture 1, 2 & 3

Hi readers! 😀

A few days ago, we watched three Christmas Lectures from the Royal Institution. This is what I learned:

#1:

  • Light bulbs could not retain its light when exposed to oxygen without the glass bulb.
  • Light bulbs could retain its light when soaked in liquid nitrogen without the bulb.
  • A light bulb has a source, a metal that produces the light. It is called the filament.
  • Light could follow the flow of a liquid.
  • LED light bulbs have a circuit board in them that could be controlled by a remote.
  • Early light bulbs use a lot of electricity.
  • Information could be transmitted from one computer (that is connected to a flashlight) to another using a type of device that functions only when the light is shone at it.

#2:

  • Alexander Graham Bell invented the telephone.
  • Videos could be projected onto fog to create a hologram.
  • Recently invented technology could simulate taste and smell of a certain item.
  • We could be influenced by our sight alone. Like when we use a type of gaming device like Oculus Rift.
  • Lots of cameras, when simultaneously used on the same subject, could create a 3D picture when stitched together.
  • There is a robot hand that could be controlled wirelessly by your own hand using a specially designed glove.
  • You could control paintball guns with a camera by connecting it to a computer and coding it.
  • You could control a sequence of something using a code.
  • There is a device that lets you feel objects that aren’t there by simulating an object.

#3:

  • Robots are made of motors, electricity, wires and metal.
  • Michael Faraday made an example of magnetism and electricity.
  • He used mercury, a metal wire, and a magnet to show that there is a magnetic field around a magnet.
  • The lecturer also showed the same magnetic field using a battery, a coil of wire, and a magnet.
  • You could use movement to generate electricity.
  • The lecturer demonstrated this using a leaf blower, a turbine, and a motor.
  • She also showed the audience a motor that makes sticks hit a drum. They are connected to a wire for the motor to control them.
  • There are examples of robots as acrobats (walking on a string), and a spider (controls its balance).
  • You could make a Rubix cube solver using a smartphone and Lego.
  • There is also a robot that could move by following a white line. It uses a sensor to guide itself.
  • The Mars Rover could move independently by analyzing Mars’ terrain. It takes pictures to send to Earth so we could learn how to navigate and travel Mars. It only has metal wheels; rubber cannot be used as it could contaminate any sign of life it finds.
  • The H5W robot plays the keyboard and it uses 60 motors and a computer.
  • There are also Pixelbots, which could tell a story and could light up. They are controlled by a camera.
  • You could make an orchestra using robots.
  • A robot plays a set of drums using MIDI (Musical Instrument Digital Interface) and coding.
  • They also turned an old printing machine into an instrument.
  • A bass guitar was made with 3D fingers connected to motors and a computer.
  • Its fingers are made using a 3D printer.
  • They used robot football players to play a keyboard. One of them gets a message and sends it on to the other robots.
  • They programmed a toy copter to play the cymbals using a controller.
  • They also made a pipe organ made of shells, and its air is from a vacuum.
  • They used a glockenspiel controlled by a computer, too.
  • The musical instruments all played the Doctor Who theme song.

That’s it for today. Thank you for reading! 😀
