Physics first

Physics provides the foundation for all natural sciences

 Physics explains the fundamental laws of the universe and introduces important concepts that are essential for advanced study of chemistry, biology and all other branches of science: 




Environmental Science                                                                                                                             Nursing

                                                 Meteorology                                                                                              Physical Therapy

Biology                                                                       Geology      

Medicine                                          Engineering

 All other branches of science


Physics is essential for understanding chemistry

Without physics students cannot understand major chemical principles, for example

  • The chemical bond
  • Gas Laws
  • Molecular collisions
  • Electrochemical studies
  • Thermodynamics
  • KE and PE Energy
  • pH

Physics and chemistry are essential for understanding biology

Without physics and chemistry students cannot understand major biology principles, for example

  • Electrical impulses and action potential
  • Electron transport, Krebs Cycle, and glycolysis
  • Muscle contraction and relaxation
  • DNA, Proteins, Lipids, Carbohydrates, ATP
  • Enzymes
  • Metabolism
  • Ion channels
  • Cell membranes
  • Blood flow to and from the lungs and heart
  • Cell division
  • Blood pressure
  • Diffusion and active transport

The last president of the National Institutes of Health was Francis Collins, a Physical Chemist. 

The Person in charge of Chemical Biology at Harvard University is a synthetic organic chemist, Stuart Schreiber.

Below is the list of biological research that received Nobel Prize. Note that the researchers were awarded Nobel Prize in the Field of Chemistry (not Biology):

                        2009   Structure and function of the ribosome

                        2008   Discovery and development of Green fluorescent protein

                        2006   Study of molecular Eukaryotic Transcription

                        2004   The discovery of ubiquitin-mediated protein degradation

                        2003   Discoveries concerning channels in cell membranes

2002   The development of methods for identification and structure 
                                    analyses of 
biological macromolecules

Physics and chemistry are essential for understanding all other areas of science

Without physics and chemistry students cannot understand major principles of any science-related field, including geology, meteorology, environmental science, astronomy, engineering, nursing, physical therapy and many others: 

  • Engineer is an applied scientist who uses physics and chemistry every day.
  •  Our space program was developed by physical chemists and physicists.
  • High and low pressures are understood through physics and chemistry.
  • A physician cannot prescribe a drug if they do not understand molecules and how they metabolize in the liver through CYT P450 deoxygenase.
  • The chemicals that are polluting the environment must be analyzed by an environmental chemist.

The list goes on. Physics and Chemistry are the Central Sciences. Without understanding these sciences you can never really understand any other sciences.
