Today I Learned
This is imo because your unconscious mind sends out a reaction. You don't use your conscious mind to decide for the appropriate reaction since that would take to long. It's like when you immediately extend your arm when you see a glass falling. Today I learned the Pangolin is the only mammal with large, protective keratin scales covering their skin. They eat mostly ants and termites and look like armadillos. https://en.wikipedia.org/wiki/Pangolin#Diet

Today I Learned
Today I learned Bacteria usually reproduce by simply dividing in two. Each new bacterium is a clone of the original, they each contain a copy of the same DNA. This is called binary fission. If conditions are just right, one bacterium could become a BILLION (1,000,000,000) bacteria in just 10 hours through binary fission! Sometimes bacteria do have a form of sex called conjugation. One bacterium reaches out to another using a thread-like structure called a pilus. The first bacterium transfers part of its DNA to the other bacterium through the pilus. By this exchange, bacteria can quickly create or pass along new traits that help them adapt to different environments.

Today I learned Water-bears (Tardigrada), microscopic multicellular organisms, can survive freezing by replacing most of their internal water with the sugar trehalose, preventing it from crystallization that otherwise damages cell membranes. Water-bears can withstand temperature ranges from 1 K (−458 °F; −272 °C) (close to absolute zero) to about 420 K (300 °F; 150 °C) for several minutes, pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without food or water for more than 30 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce. Tardigrades living in harsh conditions undergo an annual process of cyclomorphosis. https://en.wikipedia.org/wiki/Tardigrade Cyclomorphosis is the name given to the occurrence of cyclic or seasonal changes in the phenotype of an organism through successive generations. https://en.wikipedia.org/wiki/Cyclomorphosis

You seem to think philosophy you don't find useful or if you don't agree with it, then it's unsound and therefor incorrect?

Today I learned that the avocado, with its mildly toxic pit, may have coevolved with Pleistocene megafauna to be swallowed whole and excreted in their dung, ready to sprout. No extant native animal is large enough to effectively disperse avocado seeds in this fashion. https://en.wikipedia.org/wiki/Avocado#Coevolution http://io9.gizmodo.com/this-ancient-giant-armadillo-is-responsible-for-giving-1677550637 Today I also learned that one of the animals that ate the avocado were the four-tusked elephants. Those were elephant-like animals with four tusks! https://en.wikipedia.org/wiki/Gomphothere#Description

Today I learned there once lived cave lions. the cave lion ranged from Europe to Alaska over the Bering land bridge until the late Pleistocene. https://en.wikipedia.org/wiki/Cave_lion

And how do you decide which interpretation or speculation is correct or wrong?

Philosophy, Science & Reality
Many scientists also studied philosophy. I think philosophy can give you a more creative mind.

I found an interesting page concerning interpretation. https://en.wikipedia.org/wiki/Interpretation
-
Philosophy, Science & Reality
You need a 3rd party that shows which interpretation is correct.(when you interpret something) This does not exist when you deal with religion. Interpreting verses of holy book is therfor pointless, although it can give personal 'enlightenment'. In science, scientific evidence can fulfil the job of a 3rd party. Interpretations concerning quantum mechanics might turn into scientific theories based on scientific evidence.

Today I learned the Gir Forest National park in India has the last remaining Asiatic lions. These lions were once found across northern Africa, south west Asia and northern Greece.

That's true, you can't interpret the validity of measurements. But you can interpret the meaning of measurements. The bell theorem debunks local hidden variable theories. The idea that this shows an indeterministic nature of the universe is an interpretation. Gerard t hooft first developed the holographic principle. It's basically a quantum gravity model. I don't think he meant it to be part of string theory. I've read Leonard Susskind gave it a precise string-theory interpretation. He gave his own interpretation...

If interpretation is no part of it then how can physicists create different models, while they have acces to the same science?
-
Philosophy, Science & Reality
That's true. But an experiment is not necessary tied in a model. interpretation can decide in which model. Take the Holographic Principle for example. There is imo a lot that points to the validity of the Holographic Principle yet depending on your interpretation there is nothing that points to its validity. Science is very open for interpretation until there is sufficient or very strong evidence, concerning the interpretation.

Philosophy, Science & Reality
Those measurements and observations are often to open for interpretations to be 'evidence'. This causes something like the Many worlds interpretation.

Philosophy, Science & Reality
Many interpretations/theories concerning physics are not based on evidence but fit with certain measurements/observations.(like Interpretations of quantum mechanics) Are they in a sense philosophical concepts that become science when they are sufficiently proven?
