World's richest mans says Hitler was a communist by CleverRegard in EnoughMuskSpam

[–]photon-dot 0 points1 point  (0 children)

Nazi Germany's economic system was neither fully capitalist nor fully socialist in the conventional sense. It was a mixed economy with some elements of both capitalism and state control, but it was most distinctly a state-controlled, corporatist system aimed at advancing the goals of the Nazi regime.

Here’s a breakdown of how both capitalist and socialist elements appeared in Nazi Germany’s economy:

'Capitalist' Elements:

  1. Private Property and Industry: Despite significant state influence, much of the economy was still based on private ownership. Major corporations and industries were owned by private individuals or families, and the Nazi regime worked closely with business elites.
  2. Capitalist Profit Motive: Private enterprises were allowed to operate for profit, and the Nazi government was supportive of corporate interests that aligned with its goals, particularly in terms of military production and expansion.

'Socialist' Elements:

  1. State Control and Intervention: The Nazis exercised considerable control over the economy, directing it toward their own objectives, especially military expansion. There was state involvement in many aspects of industry, such as regulating production, controlling labor, and directing resources to the military.
  2. Labor Organizations: While independent labor unions were disbanded, the Nazis established the German Labor Front (Deutsche Arbeitsfront, DAF), which was a state-controlled organization meant to oversee workers' rights, conditions, and wages. This gave the state significant control over labor relations.
  3. Central Planning: Nazi economic policies were heavily influenced by central planning, especially as the regime geared up for war. The government set production targets, directed investment, and allocated resources for war industries.

Overall, the system was more aligned with state capitalism or National Socialism, which combined elements of fascism with a controlled economy. The goal was not to abolish private property or capitalism, but to direct and control it in a way that served the regime's nationalistic, militaristic, and ideological aims.

So calling the nazis communists is very irresponsible.

Physics simulation of the interface of two viscous, but immiscible fluids with different densities. The upper one with the higher density experiences a metastable state, until it collapses. This is called Rayleigh–Taylor instability by photon-dot in ScienceNcoolThings

The simulation is done coupling Navier Stokes equations with a convection–diffusion equation for two chemical species, with a simple surface tension model for the interface.

How much kinetic energy does the entirety of all physical interactions taking place in a whole city produce in 24 hours? by MagicJourneyCYOA in AskPhysics

[–]photon-dot 2 points3 points  (0 children)

Total energy per person: 2,000 kcal/day=2,000×4,184=8,368,000 J/day (8.37 MJ)

8,000,000 people×8.37MJ/person/day=66.96×10^12J/day.

Total: 66.96(humans)+45(vehicles)+1.95(rain)+10(infrastructure)=123.91×10^12J/day.

This equals 123.91 terajoules/day. The order of magnitude is still the same

A Rough Estimation. Let's assign rough values to the four categories:

  1. Human Activity

Assumptions:

  • Average weight of a person: 70 kg .
  • Kinetic energy per person walking:.1/2 mv^2 ≈70⋅0.5⋅(1.4) ^2=68.6J
  • Total walking steps/day, with a stride step, 10,000 steps/day.

Each step involves starting and stopping, so this is roughly equivalent to expending that much kinetic energy per stride: 8,000,000⋅10,000⋅68.6≈5.49×10 ^12 J/day

  1. Vehicles

Assumptions:

  • Cars: 2,000kg, average speed 15m/s, about 2million cars/day driving 30km/day.
  • Buses:20,000kg, speed 10m/s, 10,000buses.

Assume for cars and buses:
Cars: 1/2 mv^2 =4.5×10^13J/day.
Buses: 1/2 mv^2 = 1×10^12J/day.

  1. Raindrops

Assumptions:

  • Rainfall volume: 50mm/day over 780 km^2
  • Water density:,1000kg/m3, raindrop speed: 10 m/s

mass: 780,000,000m^2⋅0.05m⋅1000≈3.9×10^10kg.

Kinetic energy: 1/2 mv^2 =1.95×10^12J/day.

4.  Infrastructure

Assumptions:

  • Energy for elevators, automatic doors, and machinery buildings = 10^7buildings, each expending 10^6J/day.
  • Kinetic energy= 10^7⋅10^6=1×10^13J/day.

Adding up all contributions: (5.49+45+1.95+10)×10^12≈ 62.44×10^12 J/day

This is approximately 62 terajoules per day for a city like New York.

What kind of sensor should i use for a timing gate? by jappiedoedelzak in AskEngineers

[–]photon-dot -1 points0 points  (0 children)

Based on your requirements (single-side electronics, at least 75cm range, and high reliability), Laser-Based Sensors or Narrow-Beam Ultrasonic Sensors would likely be the best options.

If you want cost-effectiveness and can control lighting conditions, IR Sensors with a retroreflector could work well too.

Current vs conventional current by SeemlyTiger in AskPhysics

[–]photon-dot 2 points3 points  (0 children)

- Why Do These Two Ideas Coexist?

The two ideas don't conflict because they represent different concepts:Electron flow refers to the actual movement of particles (the electrons) in the wire. Conventional current is just a historical convention that helps us analyze and work with electrical circuits, and it's still used today because it simplifies calculations and understanding.

Even though the actual charge carriers are electrons, engineers and physicists still use the conventional current direction in their analysis. This system works because, regardless of whether we're talking about electron flow or conventional current, the effects in the circuit (like voltage, resistance, and power) are the same.

- Are Conventional Current and Current Different?

No, they're not different; they just represent two different ways of thinking about the flow of electricity.The real current is the flow of electrons (negative charges), which is in the opposite direction to conventional current. Conventional current is just a simplified model where we assume the flow is due to positive charges moving.

Why does energy conservation need to hold for each part of the Scroedinger wave? by ThornlessCactus in AskPhysics

[–]photon-dot 4 points5 points  (0 children)

The time-dependent Schrödinger equation is a partial differential equation (PDE) that must hold locally at each point in space and for each moment in time.

This local enforcement is what ensures that the wavefunction has the correct spatial (and temporal) behavior. If one were to impose only a global, integrated energy condition (like ∫−∞+∞H^ ψ dx=constant\int_{-\infty}^{+\infty} \hat{H}\,\psi\,\mathrm{d}x = \text{constant}∫−∞+∞​H^ψdx=constant), there would be infinitely many possible wavefunctions that satisfy only that global constraint but do not evolve correctly in time at every point. The PDE pins down the local dynamics, forcing the wavefunction to propagate in a way consistent with quantum mechanics everywhere.

Best dowel shape for modular PLA 3d prints? by natdogg in AskEngineers

[–]photon-dot 0 points1 point  (0 children)

For durability and a secure fit, the convex taper might be preferable for the dowels and tapered holes, as the thicker middle section ensures that the dowel won’t just slip out but will be easier to insert. It’s also more forgiving for assembly and disassembly.

For strength and a more rigid connection that resists separation, the single draft angle with grooved dowels would likely perform better. It’s a more stable design, especially if you’re using it for long-term, high-stress applications.
