What does it mean to repeat measurements often which are often dependent on the certainty with which an estimation can be made?

Broad Cycles in Nature that are (almost) periodic with respect to our Earth's progressive time: Growth-Decay-Growth Integration of micro-mass-Disintegration-of macro-mas-Integration. So, I see Big Bang - Universal Apocalypse-Big Bang...

There are estimated to be about (and I do mean that) 100 billion galaxies, each with an average of several hundred billion stars in it. This gives us $n =...

The light dependent reaction of provides two important requirements ATP and NADPH to the Calvin Cycle. ATP-It is a energy rich compound. The light energy is stored in it. It...

light dependent phase produces energy wheareas light independent phase utlizes the energy produced in the light dependent phase

Chloroplast is the organelle that contains chlorophyll to entrap light for photosynthesis. Chloroplast is a double membrane organelle. It has two parts, i.e. granum and stroma . Granum is made...

During light dependent reaction which is occurring in thylakoid membranes of chloroplast light energy is used to split water in to proton and molecular oxygen O2 8 Photons of light...

In the non cyclic photophosphorylation light first hits photosystem II where it excites electrons to a higher energy level. The electrons come from the photolysis of a water molecule producing...

In this reaction, oxygen is released when chloroplasts are exposed to light. In the photochemical reaction, electrons flow from H2O to NADPH2 because electrons are boosted to high energy levels...

Quantitative means measuring a quantity - putting a value to something. For example, you might measure the rate of a reaction by seeing how many seconds it takes for a...

Given what we know now, namely that contain different numbers of fundamental particles, I expect chemists (and more so physicists) would be extremely surprised if a new element appeared between...
