What is the difference between classical physics and quantum physics?

Classical Physics is based on Newtonian Physics, which is accurate for macroscopic practical daily life scenarios. The laws of physics are based on those created by Isacc Newton in the 15th and 16th century.

In 1905, Albert Einstein founded the Theory of Special Relativity which proved that Newton's laws of physics were not complete and were actually wrong. It also proved that the speed of light was a universal constant and nothing could travel faster.

Newton's laws were nearly exact in our normal lives. But when you are dealing with extremely small scale problems such as with atoms or when you dealing with great velocities, the results seem to disobey Newton's predictions. The universe behaves and was found to be much different than it first appeared!

Einsteins new equations were basically a "polished" version of Newton's equations, which applies to both low and high speeds. This is how quantum physics was founded and much of it is based on these new equations! It mostly deals with high speeds or atomic scales. Think of quantum mechanics as the "polished" version of classical physics, it tells the whole story of physics and not just an estimate.

For instance, you may not notice it when walking down a street but time slows down by an astronomically small amount and your body contracts by a very small amount, relative to the outside universe. It becomes much more apparent at extremely high speeds. As unnoticeable as it is, the effects exist everywhere.

In classic physics everything is deterministic; in quantum physics nothing is.

What is the difference between a fist bump and a pound?

A fist bump involves lightly tapping knuckles with another person, typically as a friendly greeting. A pound involves hitting fists together with more force, often as a gesture of celebration or agreement. The intensity and purpose of the action differentiate the two gestures.

What is the difference between sonic and scourge?

Sonic is blue

Scourge is green

Super Sonic's color is gold

Super Scourge's color is purple

Basically Scourge is just a bad Sonic and a copy like Sonic he has all his skills but not his super forms.

What is the difference between incoming and oncoming?

"Incoming" typically refers to something or someone that is approaching or arriving, such as incoming messages or an incoming storm. "Oncoming" specifically refers to something or someone that is approaching or moving forward, often in a direct or head-on manner, like an oncoming vehicle or an oncoming train.

Difference between center of pressure and aerodynamic center?

The CP is the average of all the pressures acting on the aerofoil and as such it will change in magnitude and position as the pressure patterns around the aerofoil changes. The biggest change will be because of changes in angle of attack.

The AC is a point on the aerofoil that does not move as you change angle of attack. If you imagine a pivot point on the trailing edge then the aerodynamic forces would make the aerofoil pivot leading edge up about that point. If you now imagine the pivot point at the leading edge then the aerodynamic forces will make the areofoil pivot trailing edge up about that point.

If that is so, then there must be a point somewhere between the leading edge and the trailing edge where there will be no change in the pitching moment of the aerofoil as the pressure pattern on the aerofoil changes. That is the AC and it is found at about 25% of the chord.

The AC is defined as a point on the chord line that :

(1) does not move as angle of attack is changed

(2) the pitching moment of a wing is always constant about it

What is the difference between radioactive and non radioactive materials?

Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.

What is difference between dextro and laevo rotation?

Useful definitions:

  • Dextro: Right
  • Laevo: Left
  • Enantiomer: mirror form of a molecule
  • Chiral: a molecule lacking an internal plane of symmetry that can be found in two non-superimposable mirror forms.

The mirror images of a chiral molecule are known as enantiomers, one will be designated Dextro (D-) and the other Laevo (L-).

This behaviour is exhibited by organic molecules containing an asymmetric Carbon atom e.g. D-Glucose, L-Cysteine, etc, enzymes are chiral and tend to selectively catalyse a single enantiomer.

Chiral molecules that are optically active will rotate plane polarised light passing through them, l- enantiomers will rotate the polarisation to the Left, d- enantiomers will rotate it to the Right.

Note the capitalisation L/D refers to the stereochemistry of the molecule relative to that of Glyceraldehyde - l/d tells you which way the polarisation will be rotated. The IUPAC discourages the use of l/d notation as it can be confusing +/- is prefered.

What are the difference between the law of conversation of energy and law of degradation?

The difference between the two is that the law of degradation implies that there is a finite non-zero amount of potential energy that is used cause a process to happen. Recent theory suggests that this is caused by the expanding universe: more energy is converted to potential energy since objects in the universe are moving further and further away from each other. It is possible to create a process that will decrease the entropy of a system (in fact that is how we are able to reach temperatures in the microKelvin range), but the overall entropy of a closed system will always be increasing.

This is different from the law of conservation of energy, which does not imply that this quantity exists. In a straight conservation of energy, it is theoretically possible for all the potential energy to converted to kinetic energy and all kinetic energy to be converted to usable potential energy.

It is worth noting that the existence of entropy does not make the law of conservation of energy wrong. Think of it this way: the law of degradation of energy is an addition to the law of conservation of energy that states that some of the energy of a system must be stored as unusable potential energy.

A real world example would be a middleman in a trade. It is theoretically possible that the middleman could buy items and sell them for the same price. However, the middleman would make no money to support himself and would starve. Therefore, he must buy items and then sell them at a higher price, thereby reserving some of the profit for himself. In this example, money would represent energy and the profit that the middleman makes represents the increasing entropy of the system. The total amount of money in the system stays the same, but the middleman must take some money for every transaction he completes in order for the system to keep functioning.

What is the difference between naturalism and non-naturalism?

Naturalism is the philosophical belief that all phenomena can be explained by natural causes without recourse to supernatural or divine intervention, while non-naturalism allows for the possibility of supernatural or non-natural explanations for certain phenomena. Naturalism tends to prioritize empirical evidence and scientific explanations, whereas non-naturalism may incorporate metaphysical or spiritual elements.

What does velocity take into account that speed does not?

Velocity takes into account the direction of motion in addition to the speed. Speed only gives the rate at which an object is moving, while velocity gives the rate and direction of the motion.

Difference between talc and diamond?

Talc is a soft mineral with a Mohs hardness of 1, while diamond is the hardest known mineral with a Mohs hardness of 10. Talc is commonly used in powder form for cosmetic products, while diamond is valued for its brilliance and is often used in jewelry and industrial cutting tools. Their hardness difference is due to their molecular structure, with diamond composed of tightly bonded carbon atoms and talc composed of loosely bonded layers of magnesium and silicon.

Can you give me some kinds of monocot and dicot plants?

A monocot seed is a seed that sprouts a single leaf, whereas a dicot seed sprouts two. Examples of monocots include rice, wheat, and garlic. Dicots include avocado, nutmeg, and cinnamon.

What is the difference between PE and KE?

PE or Potential Energy is the stored energy an object has based on its relative height or shape.

KE or Kinetic Enregy is energy in motion, or energy based on how fast an object is moving.

They may also be written as EP and EK.

What is the difference between edge and screw dislocations?

The main difference is:

The slip vector ( Burger's vector) and the line vector, which is line of atoms that dislocated, are perpendicular to each other in case of edge dislocation.

In case of screw dislocation, they are parallel to each other.

Difference between the gram stain ans acid fast stain reactions of E. coli?

Gram staining is useful in separating bacteria into two groups: Gram positive or Gram negative. They are separated into these groups based on their cell wall structure. Gram positive bacteria contain a thick layer of peptidoglycan in their cell walls, while Gram negative bacteria contain a very small layer of peptidoglycan (15% or less of what Gram positive cell walls contain). A primary stain is added, such as Crystal Violet, that will stain all of the bacteria. Then, a mordant (such as iodine and potassium iodide) is added to form a complex between the peptidoglycan and the stain, which will make the cell more resistant to decolorization. Then, a decolorizing agent is added, which will remove the primary stain from Gram negative bacteria, but will cause the cell walls in Gram positive bacteria to dehydrate, and therefore, they will retain the primary stain. Finally, a counterstain (typically safranin) is added to distinguish Gram positive from Gram negative. Gram positive cells will be purple, and Gram negative cells will be red if Crystal Violet and Safranin are used.

Acid-fast staining is entirely different. Is is used to detect species of bacteria in the genera Mycobacteria and Nocardia. These bacteria are resistant to typical staining procedures, such as Gram staining, due to a thick, waxy lipid layer in the cell wall composed of mycolic acid. Heating of the bacteria with a very strong stain such as carbol-fuchsin is necessary to "melt" this lipid layer, and force the stain through the cell wall. Once the bacteria has cooled, they will be incredibly resistant to decolorization. Non-acid fast bacteria do not contain this mycolic acid layer, and therefore, they will decolorize much easier, and are then stained with a counterstain to distinguish Acid-Fast bacteria from Non-Acid-Fast bacteria.

What is the difference between an open center and closed center system?

In a closed centre system the selector valves are generally arranged in parallel to each other. Thus hydraulic pressure is maintained at each selector valve equally and multiple devices can be operated with little degradation in performance. The closed centre valves block flow when in the neutral position and excess pressure is returned via an unloading valve or not produced in the case of a variable displacement pump.

Open centre systems pass oil straight through the centre of each selector valve when in the neutral position and return it back to the reservoir. Oil thus circulates with little or no pressure till a selection is made. All oil is then ported to the side of the actuator selected and oil from the contracting side passes back to the line to be utilised by the next selector downstream. Eventually as oil pressure builds the the open centre selector returns to the neutral position and oil pressure drops away again. Open centre systems don't require a pressure regulator and do not operate multiple systems well together. All open centre selectors are mounted in series to each other.

What does monocot and dicot mean?

Monocotyl: Fibrous root system; no cambium; no branches; parallel leaf veins; flower petals - multiple of 3; one cotyledon (MONOcotyl);

Dicotyl: Tap root system; cambium; branches; branching leaf veins; flower petals are a multiple of 4 or 5; two cotyledons (DIcotyl)

What is an Angular?

Angular is a popular front-end web application framework developed by Google. It allows developers to build dynamic, single-page web applications using TypeScript. Angular provides features like data binding, dependency injection, and components to create robust and scalable applications.

What is the difference between plans and maps?

a plan generally works using a smaller scale while a map uses a larger scale as it generally covers larger areas. a plan is a true scale scale representation while a map is drawn such that some features on it cannot be drawn to scale. on a map many features are represented as symblos and generalization is carried out reasulting in changes in scale and displacement of features. e.g on a 1:1 million map, rivers and roads may be shown but they cannot be drawn to scale. a 5m road would be 0.005mm wide if drawn according to scale.

plans tend to be for a single or few applications while maps cover a large vary of uses e.g in exploration, military, reacreation, geological, navigation e.t.c

What is the difference between holgrams and holographs?

A hologram is a recorded image that scatters the light differently in different directions, so it appears three dimensional. It is typically produced using photographic film, a laser, etc. in a process called holography.

A holograph is a hand-written document entirely written and signed by one person. It is typically produced using paper and ink pen.

What is the difference between hot wax and warm wax?

Hot wax 45-55◦C

Ingriedients: A mixture of natural resins, beeswax and microcrystalline wax.

Has low chemical reactivity and is stable. ((Sugaring: fructose, chamomile, water and citrus extracts. Azulene oil: IPM, vitamin E, azulene (chamomile extract), menthol, BHT.))

Heat opens pores and allows easier hair removal.

Applied against, with, against hairgrowth in a thick layer then solidifies and is removed (using the solid wax as a strip).

Suitable for thick, coarse hair growth and is best used in small areas such as bikini.

Gaps must be left between applications to allow skin to cool.

**HEAT IS NOT SUITABLE FOR DIABETICS ANS SENSITIZED SKIN, MAY ALSO CAUSE A REACTION AND REDNESS IS GREATER THAN WARM WAX***

Warm wax 40 - 43◦C

Ingriedients: Mainly refined gum resins and hydrocarbon tackifiers.

Glucose, Fructose, Maltose, Aqua, Citric Acid, Modified Colophonium, Solanum Tuberosum, Parfum.

Applied thinly and removed with a paper or fabric strip.

Can be applied over same area.

Applied with hair growth.

A single strip can be used until it becomes saturated with wax and hairs.

Better suited for large areas such as legs and arms than hot wax.

What is the distance between weight and mass?

Weight is the force of gravity acting on an object, measured in newtons or pounds, while mass is the amount of matter in an object, measured in kilograms or grams. They are related through the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravity.
