An absolute underestimated gem about this topic. Just one note about your final note: it's okay (actually very recommended) to look directly at it during totality. You just have to wear glasses until then, and right after the second Bailey's Beads.

It’s ironic that understanding global warming is so complex while its cause is straight forward, namely that greenhouse gases, unlike nitrogen and oxygen, readily absorb ‘infrared energy’ (heat). Absorption of such radiant energy causes these molecules to gyrate wildly and vigorously bump into neighboring molecules, thus causing them to ricochet off of other surrounding molecules that, in turn, bump into other molecules which bump into more, etcetera, etcetera. This energy of physical motion represents ‘kinetic energy’ - the measure of which is temperature. Just think of atmospheric heat as being the unified energy field of kinetic energy (physical particle action) and radiant energy (electromagnetic wave action).

The idea of controlling temperature by reducing outgoing radiation while keeping incoming radiation fixed suggests that you could somehow increase the temperature without supplying additional energy. This is fundamentally flawed due to the following reasons: The first law of thermodynamics states that energy cannot be created or destroyed, only transferred. Therefore, if the incoming energy is fixed, the total energy available to the system remains constant. If you block or reduce outgoing radiation without increasing the incoming energy, the system cannot gain more energy than what it already receives. Thus, it cannot spontaneously reach a higher temperature. For the body to reach and maintain a higher temperature, it would need to absorb more energy than it radiates until it achieves a new equilibrium. However, reducing outgoing radiation does not add more energy to the system-it only delays heat loss. The temperature of the body is set by the point where the incoming and outgoing energy fluxes are equal. Blocking radiation does not change the fixed input; it only slows the rate at which energy leaves, which doesn’t lead to a higher equilibrium temperature. The concept of "trapping" heat by blocking outgoing radiation suggests that you could increase the body's temperature by recycling its own emitted energy. This would imply a system could generate more energy than it absorbs, effectively acting as a perpetual motion machine of the second kind, which violates the second law of thermodynamics. The second law dictates that energy flows naturally from hot to cold and that energy flux cannot amplify itself without an additional external energy source. The ratio of energy out to energy in is not a controllable parameter for heating a body. It is a result of the body reaching its natural equilibrium state given the fixed incoming energy: Attempting to reduce the energy out while keeping the energy in constant does not create more energy within the system. The equilibrium temperature is set purely by the incoming energy's intensity and the body’s ability to emit radiation at a certain temperature. Imagine a lightbulb that emits heat and light when electricity is supplied: If you place insulation around the lightbulb, you might slow down heat loss temporarily, but the maximum temperature it can reach is still defined by the electrical power (energy input) supplied. The insulation doesn’t allow the lightbulb to exceed this temperature because it doesn't increase the energy input-it merely reduces the rate of heat loss. The temperature of a continuously heated body, especially one heated by radiation, is strictly determined by its equilibrium temperature, which depends on the fixed incoming radiation and its emissivity. The notion of controlling the temperature by altering the "ratio of energy out to energy in" is flawed because it violates fundamental thermodynamic principles. You cannot increase the temperature or energy content of a body by merely blocking outgoing radiation while maintaining the same input energy. This would imply a self-heating mechanism, which is impossible without adding extra energy from an external source. Thus, the body's temperature is ultimately set by the energy input and reaches an equilibrium where incoming radiation equals outgoing radiation. Any other interpretation would contradict the laws of thermodynamics. Therefore, outgoing radiation is purely a consequence of the body's temperature, which in turn is set by the energy input. It does not have a causal effect on the temperature but is instead a manifestation of it. The outgoing radiation from any object is always a downstream result of its internal temperature, which is directly determined by the energy it absorbs from its surroundings. When a body is exposed to a fixed intensity heat source, such as solar radiation or any other constant external source, its temperature will rise until it reaches a point where the energy it radiates equals the energy it absorbs-the equilibrium state. This equilibrium temperature is determined solely by the intensity of the incoming radiation. Thus, any attempt to alter the temperature without changing the intensity of the incoming heat is fundamentally impossible. The idea that you can change a body's temperature by manipulating the ratio of incoming to outgoing energy is a misunderstanding of how thermodynamic systems work. The ratio itself is not a controllable parameter but an outcome of the body's internal temperature responding to the fixed energy input. In a passively heated system, you cannot influence this ratio independently because the outgoing energy will always adjust to match the incoming energy at equilibrium. The only scenario where you can actively control the ratio of energy out to energy in is when the body has an internal heat source capable of producing energy, such as a heat engine, a chemical reaction, or an electrical heater. A body cannot spontaneously heat faster than it would when exposed to a constant stream of thermal radiation, without the introduction of an additional energy source or mechanism that actively adds energy to the system. This is constrained by the first and second laws of thermodynamics, which govern how energy flows and is converted. When a body is exposed to a constant stream of thermal radiation, it absorbs energy at a specific rate determined by the intensity of the radiation, the body's surface area, emissivity, and absorptivity. As it absorbs energy, the body's temperature rises, which in turn increases the amount of energy it radiates back into its environment until it reaches a point of thermal equilibrium where the incoming and outgoing radiation are balanced. The first law states that energy cannot be created or destroyed, only transferred or converted. For a body to heat faster than what the incoming thermal radiation alone can provide, it would need access to additional energy beyond the steady radiative input. In the absence of such an external source, the body can only heat at the rate dictated by the incoming radiation. The second law states that heat flows from hotter regions to cooler regions, and systems naturally evolve towards thermodynamic equilibrium without external intervention. For a body to heat more rapidly than what the radiation provides, it would imply an increase in internal energy beyond what is supplied, which would violate this law. Energy can't spontaneously accumulate at a faster rate than the energy input allows. While spontaneous acceleration in heating isn’t possible, certain mechanisms can cause a body to heat faster, but they require external intervention: Focusing or Concentrating Radiation: Using lenses or mirrors to concentrate thermal radiation onto the body could increase the rate of energy absorption, causing it to heat faster. However, this isn't spontaneous, as it involves an external setup to direct additional energy to the body. Heat Conduction or Convection: If another hotter object were placed in contact with the body or in its proximity, heat transfer through conduction or convection could increase its heating rate. Again, this isn't spontaneous because it involves introducing an external heat source. If the body underwent a chemical reaction or phase change that released energy (e.g., an exothermic reaction), it could warm faster. But this would require an initial trigger or catalyst, and the reaction is an additional source of energy, not spontaneous self-heating from radiation alone. Misconceptions about Self-Amplifying Heat The idea that a body could "heat itself" faster than the input energy permits is similar to the concept of a perpetual motion machine of the second kind, which the second law of thermodynamics forbids. This is because: To heat faster than the incoming radiation suggests that the body would be generating extra energy internally or amplifying the input energy, which is impossible without violating fundamental physical laws. Conclusion In the scenario where a body is bathed in a constant stream of thermal radiation, it can only heat at the rate determined by that radiation. It cannot spontaneously heat faster than this rate because doing so would violate the principles of energy conservation and the second law of thermodynamics. Any mechanism that increases the heating rate would require external intervention or an additional energy source, meaning it is not spontaneous or self-generated. christophepocharienergietechnik.com/2023/01/06/the-greenhouse-effect-the-largest-scientific-error-in-human-history/

You people repeating what NASA is telling you, fucking lies. The Earth is of the Geocentric model, with the Earth at the Center. Ancient Cosmology is very convincing explaining Polaris's role and functions of the Compass. Keep believing in NASA, Religion, and Government. Humanity's greatest downfall, belief Systems.

I want to build an app for a retirement home housing 150 aged residents. They will need access to the app to record their daily options for Meal choices and absences. I want each resident (user) to login to the app with a password or some unique ID like their phone number, but not the e-Mail ID because most of them do not have it. Can this be done in Glide?
