Timely quotes about science: Science Rules

Hi there! Greetings from the blog-verse. Here I share some interesting, inspirational, and timely quotes about science from some of the greatest minds of our time. Enjoy and remember the wisdom of these wise men.



"Change will come slowly, across generations, because old beliefs die hard even when demonstrably false"  E. O. Wilson

"We are drowning in information while starving for wisdom. The world henceforth will be run by synthesizers, people able to put together the right information at the right time, think critically about it, and make important choices wisely"  E. O. Wilson

"Political ideology can corrupt the mind and science" E. O. Wilson


"There is no greater education than the one that is self-driven" Neil deGrasse Tyson


"Science simply tells the best stories" Neil deGrasse Tyson

"When you make the finding yourself even if you're the last person on Earth to see the light, you'll never forget it" Carl Sagan


"Science rules" Bill Nye

Public Connotation : Theory or Hypothesis?


Most people do not know the difference between a theory and a hypothesis. These two terms hold different connotations and meaning for the public than does for scientists--or at least science trained.

In science, a theory is a well-supported fact. It is supported and corroborated by many tests or experiments and observations. Examples of theories in science include the theory of evolution in Biology, the theory of plate tectonics, theory of gravitation, the theory of Relativity, and the laws of photoelectric effects(which by the way is one of Einstein's greatest contribution to science which gained him the Nobel Prize in theoretical physics in 1921, but I digress). These theories are not conjecture and are considered facts because they have been proven over and over again, consistently, and are in a way, predictable. No serious person, in my opinion, doubts gravity. 

A scientific hypothesis is a question or idea that remains to be proven--meaning it is not yet quite a theory or law; more observations and experimentation is needed to corroborate it or disprove it. For example, the hypothesis that dinosaurs were warm-blooded, or whether natural selection is the main mechanisms of speciation--the source or origin of species, or the currently hot hypothesis of human-induced climate change. These are scientific hypotheses. 

An important aspect of hypotheses is that they must make testable predictions. If a hypothesis does not make a prediction or gives it certain qualities that allow the researcher to test it, then the hypothesis make the logical fallacy of being empty. An empty hypothesis thus makes no prediction and is untestable. One could never know whether is true or conjecture and would have to speculate always on its foundation. An example of this is that of the Bermuda Triangle, but that's for another post. These are the meaning of a scientific theory and hypothesis as intended.

The public, however, uses the term theory with another meaning. For instance, the theory that Big Foot exists, or the theory of Kennedy's assassination, or even of ancient aliens, gave rise to our most important civilizations. These in reality, if there is any serious intention, are only hypotheses. They still require much more convincing evidence in order to be proven or disproven. But they are by no means theories or laws, they are still hypotheses.

So there, the public confuses the meaning of the terms hypothesis and theory. You may hear it on the news or read it on social media. But these vehicles only seem to obscure and contort the meaning of these two terms, which results in a confused usage by the public, leading to the misusage of the term theory when is really meant hypothesis.

I recommend, although in my very own biased way, two books that can expand on these topics, and help in our ever-continuous battle against science illiteracy in the World. One is "Unscientific America: How Scientific Illiteracy Threatens our Future" (2010) by Chris Mooney and Sheril Kirshenbaum, Basics Books, New York. The second is Donald Prothero's (2007) "Evolution: What the Fossils Say and Why it Matters" Columbia University Press, New York.

Why Do I Blog?


Most of us blog to communicate ideas, discoveries, news, and the excitement that accompanies discovery. I started this blog with the intention to promote and divulge interesting ideas and information about the sciences that study the past, and the understanding I have gathered through my own experience in learning and research. This, of course, is with the hope of reaching a curious and interested audience.


This ideal is important for several reasons. One is that most of the scientific data we gather through field and cabinet work is later published in specialized journals, but these journals and their content are not really accessible to the general population. Moreover, people do not have the time to keep up with the amount of articles and journals published at all times, or because they are difficult to read.

These create a breach between the most recent scientific discoveries that is of value or interest to us all. Unfortunately, this breach is also a source of mistrust and unhealthy-biased skepticism for science in general, largely due to misunderstanding or ignorance. In fact, this goes against the grain of science communication and education, and it creates a deep gap between mainstream scientific advance and public knowledge.

I have hoped to contribute, although I recognize on a smaller scale, by posting about the things that I am curious about in science, promoting the scientific rationale behind them, and my personal experiences in my journey of learning and researching within these fields. I try to explain processes to find the practicability, or even really the excuse for what we do.

But what is the excuse. What if that curiosity pays off in the long run? It does. Curiosity does pay off in the long run. Look around you. The world that surrounds us is a world created by curiosity, science and technology. Think of the computer or cell phone in which you read these lines. The principles that make these appliances are hundreds of years old, invented or idealized by curious people who had no idea that their curiosities will turn out to be practical or useful to societies of the future.

As a geoscientist, I am trained to use the present as the key to the past. We are constantly trying to recreate and reconstruct the past. But, we try to reconstruct the past in the hope that that knowledge will give us a better present and future. We use models and predictions to hypothesize and reconstruct both the past and the future. So can we reconcile what we do with the practicability of our curiosity in the scheme of time? I think so. Discovering something new or interesting is one of my greatest pleasures. If the present is indeed the only reality and a product construction of our minds, then what better way to spend one's lifetime trying to understand the world that surrounds us, the things that draw our curiosity, even if at the time they seem impracticable or useless. Most of all, sharing and distributing that knowledge makes the quest most rewarding. I think that time has shown that in science no discovery is useless. We must surely always try to answer the whys, and how, where and who of our curiosity, and science allows for that freedom of thought and exploration that can surely fill more than a lifetime, and no doubt continue to better society and enrich human life.
