    Wow, that is an interesting question.
    An electron is one of a few particles that are unique in nature. It is a lepton, and it appears not to be made of smaller particles like the proton and the neutron, which are made of quarks.
    The electron is very small and when it moves it behaves much like a photon, which is a wave particle that oscillates like a wave on a string. When an electron revolves around a nucleus of an atom it does so like a wave and the orbit is an integer number of wavelengths (1, 2, 3, etc)
    An electron in a hydrogen atom travels around the nucleus six thousand trillion times per second
    that is (6,000,000,000,000,000) times per second.
    We don't fully understand what gives a particle charge or what charge actually is. Quarks have even more strange properties that attract and repel other quarks. It is still a big mystery to us.

      @@MichelvanBiezen WHY AND HOW TIME AND SPACE ARE MATHEMATICALLY, CLEARLY, AND NECESSARILY PROVEN TO BE CONSISTENT WITH WHAT IS THE FOURTH DIMENSION:
      BALANCE AND completeness go hand in hand.
      Are the second dimension and the fourth dimension consistent? Are they, in turn, consistent with TIME AND time dilation ON BALANCE? Are they consistent with what is the EYE (ON BALANCE)? Note: The stars AND PLANETS are POINTS in the night sky.
      The answer is: Yes. ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE).

    Dear professor, I love phyisics and your lectures are great.
    Here are my questions:
    If two negative charges are placed at a distance n, they should repell each other, for they're both negative. However, their electric fields are pulling towards each of them!
    So why do two negative charges repell each other?
    Coming back at this video's example, what would happen if an electron was placed there? My guess is that it would be repelled by the total electric field, because the directions of the forces of the two charges would be inverted.
    Thank you very much for the time and passion you're putting into all of these awesome lectures!

    • @MichelvanBiezen
      @MichelvanBiezen  8 ปีที่แล้ว

      When a negative charged is placed at a particular location, it will create an electric filed directed towards the negative charge. If you now place a second negative charge nearby, it will experience a force away from the first charge. (Negative charges experience a force in the opposite direction of the electric field. The first charge will experience a force away from the second charge caused by the interaction with the electric field caused by the second charge.

      anytime the probe charge isn't specified I.e. the point where you find the electric field, we assume that the probe charge or point where we want to find E is postively charged therefore the - charge has a force to the right and the positive to the right as well so fnet or E is right

    • @MichelvanBiezen
      @MichelvanBiezen  6 ปีที่แล้ว +1

      There is no difference between q and Q. Typically we use q for a little charge and Q for a big charge. If the source charge of the electric field is known we use E = kQ/R^2 If the force is known, or you want to know the force, or you need to use the definition, you use E = F/Q

      @@MichelvanBiezen THE MATHEMATICAL AND PHYSICAL PROOF THAT E=MC2 IS DIMENSIONALLY CONSISTENT WITH ONE AND WHAT IS A TWO DIMENSIONAL SURFACE OR SPACE ON BALANCE, THEREBY PROVING THAT ELECTROMAGNETISM/ENERGY IS CLEARLY AND NECESSARILY PROVEN TO BE GRAVITY (ON/IN BALANCE):
      This also clearly proves ON balance that E=mc2 is directly taken from F=ma. Magnificent.
      Gravity is a property of SPACE ON BALANCE. It involves adherence or cohesion. So, BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE. Accordingly, ON BALANCE, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Consider what is the man who IS standing on what is THE EARTH/ground (ON BALANCE). What is the blue sky ON BALANCE? This IS the blue EARTH AS this is expressed on balance WITH (or equivalently by) what is the eye. The translucent AND blue sky is consistent with what is BALANCED BODILY/VISUAL (AND electromagnetic/gravitational) EXPERIENCE ON BALANCE, as touch AND feeling BLEND; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). GREAT. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE !! Consider TIME (AND time dilation) ON BALANCE. E=mc2 IS F=ma ON BALANCE, AS the rotation of WHAT IS THE MOON matches it's revolution; as ELECTROMAGNETISM/energy is CLEARLY (AND necessarily) proven to be gravity (ON/IN BALANCE). The tides are CLEARLY and necessarily proven to be electroMAGNETIC/gravitational ON BALANCE. I have also CLEARLY explained (ON BALANCE) why THE PLANETS move away very, very, very, very slightly in relation to WHAT IS THE SUN !! I have explained why WHAT IS THE EYE beholds what is then (ON BALANCE) WHAT IS THE BLUE EARTH. Notice the associated black “space” AND DOME regarding what is the eye. Again, the stars AND PLANETS are POINTS in the night sky ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Very carefully consider what is THE SUN ON BALANCE !! E=mc2 IS F=ma. Again, I have proven AND explained why the rotation of WHAT IS THE MOON matches it's revolution.
      Gravity cannot be shielded (or blocked) ON BALANCE. What is quantum gravity is CLEARLY fundamental ON BALANCE. Gravity is CLEARLY fundamental ON BALANCE. BALANCED inertia/INERTIAL RESISTANCE is fundamental ON BALANCE.
      Define “mass". You cannot. BALANCED inertia/INERTIAL RESISTANCE is fundamental.
      E=mc2 is taken directly from F=ma. CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); as the stars AND PLANETS are POINTS in the night sky !! Consider TIME (AND time dilation) ON BALANCE. GREAT.
      You have to CLEARLY AND fully understand what E=mc2 means and represents ON BALANCE.
      We want to understand the dimensions in a seamless (or balanced) fashion in relation to gravity AND ELECTROMAGNETISM/energy (including what is E=mc2). Consider one AND three dimensional SPACE ON BALANCE. Consider what is the fourth dimension ON BALANCE. NOW, consider all of the following.
      Consider what is E=mc2. CLEARLY, you have to understand what is a TWO dimensional surface OR SPACE ON BALANCE. c squared CLEARLY represents BALANCED acceleration in conjunction WITH what is NECESSARILY a dimension of SPACE ON BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE, AND consider what is the speed of light (c) ON BALANCE. This CLEARLY AND NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual ON/IN BALANCE. Carefully consider what is THE EYE ON BALANCE. Great. Consider what is gravity AND E=mc2 ON BALANCE.
      TIME dilation ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS the stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE. The stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, it makes perfect sense that THE PLANETS (including WHAT IS THE EARTH) will move away very, very, very slightly in relation to what is THE SUN !!! ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/ENERGY, as this balances gravity AND inertia; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. GREAT.

    Similar electric fields of electrons/protons repel each other. But an electron/proton has similar field around it. How similar electric field of electron or proton hold together. It should repel itself & disintegrate. This can only happen if we imagine the 'particles' which make up electric field around electron/proton have both negative & positive electric poles in opposite direction. This will sticks these particles together & behave just like iron filling in a magnetic field of north or south pole.
