Appropriate experiments showed that this is, indeed, possible.

Instead, his chemical experiments showed barium as a product.

Working with Pierre-Simon Laplace, Lavoisier conducted experiments that showed that respiration was essentially a slow combustion of organic material using inhaled oxygen.

Until recently, it was believed that some experiments showed the existence of pentaquarks — " exotic " baryons made of four quarks and one antiquark.

Also, while elementary particles showed predictable properties in many experiments, they became highly unpredictable in certain contexts, for example, if one attempted to measure their individual trajectories through a simple physical apparatus.

Breeding experiments in Germany with poodles, coyotes, and later on with the resulting dog-coyote hybrids showed that, unlike wolfdogs, coydogs exhibit a decrease in fertility, significant communication problems, and an increase of genetic diseases after three generations of interbreeding.

Videos of rod-shaped objects moving quickly through the air were claimed by some to be alien life forms or small UFOs, but subsequent experiments showed that these rods appear in film because of an optical illusion / collusion ( especially in interlaced video recording ).

According to Karl Popper these experiments showed that the class of " hidden variables " Einstein believed in is erroneous.

In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not.

Moseley's experiments in X-ray spectroscopy showed directly from their physics that cobalt and nickel have the different atomic numbers, 27 and 28, and that they are placed in the Periodic Table correctly by Moseley's objective measurements of their atomic numbers.

Results of scientific experiments published in 1976 involving Kirlian photography of living tissue ( human finger tips ) showed that most of the variations in corona discharge streamer length, density, curvature and color can be accounted for by the moisture content on the surface of and within the living tissue.

His experiments showed a correspondence between electron energy levels and the colors recorded on the film.

Also, subsequent experiments as the Sagnac effect ( 1913 ) also showed that is model is untenable.

However, Hendrik Antoon Lorentz ( 1895 ) modified Fresnel's theory and showed that those experiments can be explained by a stationary aether as well:

In addition, the interference experiments of Lodge ( 1893, 1897 ) and Ludwig Zehnder ( 1895 ), aimed to show whether the aether is dragged by various, rotating masses, showed no aether drag.

1 ) between dominant and recessive phenotypes, his experiments with mixing two traits ( dihybrid cross ) showed 9: 3: 3: 1 ratios ( Fig.

It also had about the right mass, and over the next few years, more experiments showed that the pion was indeed involved in strong interactions.

Even after experiments showed that Einstein's equations for the photoelectric effect were accurate, resistance to the idea of photons continued, since it appeared to contradict Maxwell's equations, which were well-understood and verified.

His experiments showed very high positive results.

Richard Feynman argued that high energy experiments showed quarks are real particles: he called them partons ( since they were parts of hadrons ).

Recent research with non-linguistic experiments in languages with different grammatical properties ( e. g. languages with and without numeral classifiers or with different gender grammar systems ) showed that there are — to a certain degree — differences in human categorization due to such differences.

In his UHF experiments, he transmitted and received radio waves over short distances and showed that the properties of radio waves were consistent with Maxwell ’ s electromagnetic theory.

The double-slit experiments showed that when light is sent through a grid, a characteristic interference pattern is observed, very similar to the pattern resulting from the interference of water waves ; the wavelength of light can be computed from such patterns.

At that time, the wave model of light — specifically, the Maxwell theory of electromagnetic radiation — was well accepted among scientists, and experiments by Charles Glover Barkla showed that X-rays exhibited phenomena associated with electromagnetic waves, including transverse polarization and spectral lines akin to those observed in the visible wavelengths.

The large number of experiments exploring the physics and chemistry of these so-called " colloidal crystals " has emerged as a result of the relatively simple methods that have evolved in the last 20 years for preparing synthetic monodisperse colloids ( both polymer and mineral ) and, through various mechanisms, implementing and preserving their long-range order formation.

As can be shown using simple thought experiments following the free-fall trajectories of different test particles, the result of transporting spacetime vectors that can denote a particle's velocity ( time-like vectors ) will vary with the particle's trajectory ; mathematically speaking, the Newtonian connection is not integrable.

It also seems that she could know on the basis of simple thought experiments that she can only think that water is wet if she lives in a world that contains water.

A relatively simple Farnsworth – Hirsch fusor can be used to generate neutrons for NAA experiments.

In a series of experiments, Barrouillet and colleagues have shown that memory for lists of letters depends on cognitive load, but not on the number of processing steps ( a finding that is difficult to explain by an interference hypothesis ) and not on the total time of processing ( a finding difficult to explain by a simple decay hypothesis ).

His " driving " experiments consisted of putting subjects into drug-induced coma for weeks at a time ( up to three months in one case ) while playing tape loops of noise or simple repetitive statements.

Having this simple but essential mathematical proportion at hand – which proved the overall impossible aforementioned role of the liver – Harvey went on to prove how the blood circulated in a circle by means of countless experiments initially done on serpents and fish: tying their veins and arteries in separate periods of time, Harvey noticed the modifications which occurred ; indeed, as he tied the veins, the heart would become empty, while as he did the same to the arteries, the organ would swell up.

Lab experiments on the photochemistry of simple interstellar ices have produced amino acids.

While teaching there, Oppenheimer became increasingly interested in teaching science through simple hands-on experiments, eventually moving on to found the Exploratorium in San Francisco.

Although such experiments are relatively easy to perform, their mathematical interpretation is far from simple: there may be more than one locally minimizing surface, and they may have non-trivial topology.

Case studies aside, modern experiments have demonstrated that the relation between brain and mind is much more than simple correlation.

* Elementary science should focus on simple natural phenomena ( nature study ) by means of experiments carried out " in-the-field.

Through a series of thought experiments, this book explores the development of complex robot behaviours through simple inhibitory and excitory sensor links to the actuators.

* Conrad, James M., and Jonathan W. Mills, " Stiquito: advanced experiments with a simple and inexpensive robot ", The future for nitinol-propelled walking robots, Mark W. Tilden.

Amateurs were welcome to perform simple experiments on site to enhance their knowledge.

A simple consequence of the fluctuation theorem given above is that if we carry out an arbitrarily large ensemble of experiments from some initial time t = 0, and perform an ensemble average of time averages of the entropy production then an exact consequence of the FT is that the ensemble average cannot be negative for any value of the averaging time t:

The experiments, many of which seemed impossible at first glance, were usually simple enough to be re-created by viewers.

Experiments on Hebbian synapse modification mechanisms at the central nervous system synapses of vertebrates are much more difficult to control than are experiments with the relatively simple peripheral nervous system synapses studied in marine invertebrates.

The use of rules has sometimes been considered an ability restricted to humans, but a number of experiments have shown evidence of simple rule learning in primates ( e. g. ) and also in other animals.

It is demonstrated that this proposal can be realized in present experiments with bosonic mixtures in an optical lattice that features simple on-site interactions.

The students have been introduced to the various elements of the Rosicrucian system and had the opportunity to practice many of the principles presented through simple experiments.

The experiments stand as a warning about simple experiments on human participants viewed as if they were only material systems.
