Famous experiments that changed the world include:
Pavlov's experiments.
The double slit experiment.
The golden ray experiment.
Explanation:
Pavlov's experiments are the groundwork of much of the work that is done in the modern day in the field of psychology.
It is based on the concepts of classical conditioning and how stimuli and response makes our response behaviors work.
The double slit experiment is also one of the fundamental experiments that opened up the field of quantum physics.
The experiment was done to deflect and dissect beams of light through microscopic slits.
The golden ray experiment is responsible for the foundation of the structure of atom and how it was discovered.
A ray of light was made to fall on a gold foil and then its trajectory was noted as the form of the experiment.

People who need life-saving drugs cannot do without them and surely will be willing to pay very high prices for them because a monopolist, such as one selling life-saving drugs, still faces downward-sloping demand curves.
Drugs are chemical substances that, when consumed, cause changes in the physiology or psychology of living organisms. Pharmaceuticals are generally distinguished from foods or substances that provide nutritional supplements. Drugs are consumed by inhalation, injection, smoking, ingestion, absorption through skin patches, suppositories, or sublingual dissolution.
In pharmacology, a drug is a chemical substance, usually of known structure, that produces a biological effect when administered to a living organism. Pharmaceuticals, also known as drugs or medicines, are chemical substances used to treat, cure, prevent, diagnose, or promote health. Medicines have traditionally been obtained by extraction from medicinal plants, but more recently they have also been obtained by disorders of organic synthesis.
