Henri Becquerel was convinced that his hypothesis about the spontaneous emission of radiation from uranium was supported when he observed that uranium chloride crystals exposed to sunlight could fog a photographic plate wrapped in opaque paper. This suggested that something unseen was being emitted by the uranium that could cause this effect.
The Matching hypothesis was first proposed by Elaine Hatfield and her colleagues in 1966. It posits that individuals are attracted to and form relationships with others who are of similar attractiveness and social desirability.
Marie Curie, Pierre Curie, and Henri Becquerel were key scientists involved in the discovery of radioactivity in the late 19th and early 20th centuries. Marie Curie's work with radioactive materials led to her pioneering research on radioactivity for which she was awarded Nobel Prizes in Physics and Chemistry.
A hypothesis become a theory if it is proved by experimental data. tested; conclusion (apex)
Alexander Fleming used the scientific method by making observations of mold killing bacteria in a petri dish, forming a hypothesis that the mold could have antibacterial properties, testing this hypothesis through experiments, and analyzing the results to draw conclusions. His systematic approach led to the discovery of penicillin, the first antibiotic.
A hypothesis for fractional distillation could be: "I hypothesize that fractional distillation will separate a mixture of liquids into its individual components based on their boiling points, with the lower boiling point component distilling off first and the higher boiling point component remaining in the flask, resulting in a purer distillate."
Becquerel initially believed his hypothesis that phosphorescent materials produce X-rays when exposed to light was correct because he observed that the photographic plates placed next to uranium salts, a phosphorescent material, became fogged even when stored in the dark. This led him to conclude that some invisible radiation was being emitted from the uranium salts.
test your hypothesis.
That's the first step.
A scientific hypothesis is an "educated guess" about a result or solution based on prior knowledge and observation. It is the first step in the scientific method. The hypothesis must be something that can be supported or defended through experimentation or observation.
Drop two balls with different weights and observe which ball hits the ground first.
Radioactivity was first discovered in 1896 by the French scientist Henri Becquerel.
A hypothesis is an educated guess. In science, when you are given a question or if you want to examine something, you first have to question being asked, which is important to define. Then you need to decide what you think the answer is. This is your HYPOTHESIS. After you have it, you design an experiment to test it. Based on that experiment, decide whether or not your hypothesis is supported by your results. Then you can either adjust your hypothesis or figure out new ways to test it. Science marches on!
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.
The Scientific Method first starts with formulation of a question. Any question that is testable will do. The next step is to come up with an educated guess about your question. After the guess is made a prediction about the hypothesis (usually whether it is correct or not) is made. You then next test your Hypothesis using an experiment. After you test your Hypothesis you Analyse the data to discover whether or not the prediction about the Hypothesis is, or is not, supported.
The best answer if we have to limit it to a single individual is probably Henri Becquerel.
To make a hypothesis in a scientific experiment, first, identify the problem or question you want to investigate. Then, research existing information and observations related to the topic. Next, propose a possible explanation or prediction based on this information. Finally, ensure that your hypothesis is testable and can be supported or refuted through experimentation.
