- 3041 - QUANTUM MECHANICS - controlling our reality? This review discuss the strange world of Quantum Mechanics and suggests that it is really controlling our reality below the surface. Quantum behavior may be what allows birds to fly thousands of miles with precise navigation. It may be what allows plants to synthesize sunlight. It may be what links your brain to eyesight.
--------------- 3041 - QUANTUM MECHANICS - controlling our reality?
- A measured atom is described much differently than an unmeasured atom. At the atomic level the process of measurement changes the unmeasured attributes. So, once we know what something is it isn’t that anymore.
-
- When you remove information the thing changes. Reality always exists with uncertainty as to what is really there.
-
- The measured attributes are the ones we learn and know about. We think that is reality.
-
- There is a totally unreasonable effectiveness of how mathematics describes the reality we observe. We get answers and predictions from math that are totally accurate to what nature does. It is like math is something we have discovered, not something we have invented to explain things.
-
- Light is a special oscillation, it oscillates only sideways. It does not have back and forth vibrations. Sound waves on the other hand vibrate back and forth. Seismic waves from earthquakes vibrate in all directions. Electromagnetic radiation only vibrates sideways and only moves forward at one speed, 670,633,500 miles per hour.
-
- Motion can only be defined in relative terms. There is no way to identify absolute motion. It is always relative to something else. Motion is distance ( space ) over duration of time. Both distance and time only exist if you have a start and stop in both time and place. Motion is the change in space-time. Velocity = delta x / delta t
-
- However, space and time appear different for each observer. Space and time themselves change in combination with motion and velocity to keep physics the same for every observer. Space and time modify themselves so the reality of physics remains the same everywhere regardless of where you are or how you are moving.
-
- There is no reality in the absence of observation. Observation always removes information.
-
- Gravity links everything in the Universe. However, the strength of gravity diminishes with separation. Quantum Mechanics links everything in the Universe. But, Quantum Mechanics is undiminished with separations in space or time.
-
- Gravity is not a force but a curvature of 4 dimensions of space-time.
-
- Quantum Mechanics is a theory of the probability of occurrences and not representing the things themselves.
-
- Consciousness creates reality. Without consciousness there is no reality.
-
- Physics is composed of the laws of nature and the laws of fields. Electromagnetic, gravitational, strong and weak nuclear fields. We call them forces but fields is how forces exist. Gravity is referred to as both a field of potential energy and a geometry of space-time.
-
- Light is created by the motion of electrons. Photons are massless particles that are emitted when electrons change energy levels. It could be in the energy levels orbiting an atom, or, it could be the kinetic energy of an acceleration electron.
-
- All energy comes in bunches called quantums.
-
----------------------------- Light energy = n*h*f
-
-------------------“n” is the number of bunches, or quantums.
-
--------------------“h” is Planck’s Constant of Action which is the action energy of one bunch, or one photon.
-
------------------ h = 6.625 * 10^-34 kilograms * meters^2 / second
-
------------------- h = 4.136 * 10^-15 electron volts * seconds / cycle
-
- Seconds / cycle is the time of one wavelength. Cycles / second is the frequency of vibration , or the frequency of oscillation.
-
- “f” is the frequency of oscillation of the radiation. Frequency is cycles per second. Wavelength is meters per cycle. Frequency * wavelength is the speed of light ,”c”, in meters per second.
-
--------------------- f * w = c
-
- The frequency of light is also the color. Wavelengths of light is the color:
-
---------------------- red = 700 nanometers per cycle
---------------------- yellow = 600 nanometers per cycle
---------------------- blue = 400 nanometers per cycle
-
- Frequency of colors:
---------------------- red = 429,000,000,000,000 cycle per second
---------------------- yellow = 500,000,000,000,000 cycles per second
---------------------- blue = 750,000,000,000,000 cycles per second
-
- Color and frequency are also the temperature of whatever is emitting the light:
-
---------------------- red = 4,143Kelvin
---------------------- yellow = 4,833 Kelvin
---------------------- blue = 7,250 Kelvin
-
- Our Sun is 6,000 Kelvin and blue-green in color. Our atmosphere takes out the blue making the Sun look yellow.
-
- Momentum is mass * velocity ( p = m* v ) , but , for a massless particle like light momentum is Planck’s Constant of Action * wavelength
-
----------------- E = h * f -------- photon energy
-
------------------ p = h * w --------- photon momentum
-
- Physics is the science that matches mathematics to measurement results.
-
- There exist paired relationships in reality that restrict the precision of mutual measurements. These pairs include position and momentum, since momentum is mass * velocity it is position and velocity, and energy and time. The formula for the precision the mutual measurement can obtain is:
-
------------------- delta p * delta x must be greater than “h”
-
------------------ change in momentum * change in position > Planck’s constant of action
-
------------------ We freeze time to get a wave’s position in space.
-
------------------ We freeze space to get a wave’s picture in time.
-
----------------- The trade-off is the better we know position the less we know velocity and vice versa.
-
- Intensity is proportional to a wave’s amplitude squared. Amplitude squared is a measurement of probability. Probability is the relative number of ways a particular event can occur. Quantum randomness can cause identical situations to give different results. It all depends on their probabilities.
-
- Any wave can be written as a unique sum of sine waves. This is Fourier Analysis.
- An atom is 1,000 times smaller than the wavelength of green light. 0.5 nanometers versus 500 nanometers. A nucleus is `10,000 ties smaller than an atom 0.00005 nanometers versus 0.5 nanometers.
-
- A confined wave can be made to vibrate only at certain resonant frequencies or wavelengths. This is how the klystron or magnetron works in a microwave oven.
-
- We tend to thing of Quantum Mechanics as another world. A strange world, unfamiliar, counter intuitive, not the reality of classical physics. It only applies to small things like atoms and classical physics works for everything we can see and touch, our reality. However, once we understand the quantum rules we learn they are working on all scales.
-
- Quantum Mechanics is operating in each cell in our body. It is used by your brain to make pictures of what your eyes receive. It allows birds to navigate thousands of miles using the Earth’s magnetic field to guide them. We have to start thinking of Quantum Mechanics as our world of reality
-
- Classical physics hides Quantum Mechanics because it becomes a combination of many things, many events. Classical physics can always be broken down into a sum of its parts. Quantum effects like entanglement binds individual particles together into an indivisible whole. They can not be broken apart.
-
- Even when separated far apart entangle particles operate as a single whole. Entangled electrons will always spin in the opposite direction, one clockwise and the other counter-clockwise no matter which way you measure them.
-
- Entanglement may be the secret nature uses for photosynthesis, the process plants use to convert sunlight into chemical energy. In classical physics we see one particle in one place and one time. In Quantum physics a particle can be in many places simultaneously. It is counterintuitive. Space and time somehow emerges from fundamentally spaceless and timeless physics.
-
- Gravity may be the residual noise that emerges from the quantum fuzziness of the Quantum Universe we live in. If so, gravity may not even exist at the quantum level.
-
- Entanglement may be what causes all this confusion and wonderment that nobody understands. It may be what creates consciousness. An announcement will be made soon, stay tuned while I try to figure this all out.
