Croatia’s contribution to science from the 20th to 21st century

Ivan 'Juan' VuceticCroatia stands at the crossroads of the Balkans, the Mediterranean and Central Europe. Its first inhabitants were Neanderthals in the prehistoric age as evidenced by fossil discoveries in the country’s north. Although relatively small in geographical size, it’s history reveals a country that has produced some of the most prominent people in various fields of study.

When the importance of oil in driving the world’s economy is discussed, the name, Antun Lucic gets little or no mention. Born in Split, Croatia in 1855, Antun moved to America where his name was conveniently changed to Antony Lucas. He took his studies at the polytechnic of Graz where he studied mining engineering and was later to be known as the father of the petroleum industry after his discovery of the first Texas gusher. This discovery was responsible for the population build up in a town called Spindletop from 8,000 in 1901 to over 60,000 people in 1902. Again, it was because of this discovery, that America overtook Russia as the leading producer of oil. Continue reading Croatia’s contribution to science from the 20th to 21st century

Croatia’s contribution to science from the 15th to 19th centuries

Ivan Lupis VukicCroatian science made leaps between the 15th and 19th centuries. It was the period of awakening when it came to new discoveries that later made a lot of changes with the way things were seen at that time. Particularly, this era proved to be one of the golden times in Croatian history because of the influence of some prominent personalities during that period.

Some of the noted Croatian Personalities that became famous during that era were listed below:

Mark Antun de Dominis (1560-1624) – is considered as one of the greatest philosophers and scientist during his time. He especially earned the good graces of King James I and was given the nobility Continue reading Croatia’s contribution to science from the 15th to 19th centuries

Ever Wondered What Is Dark Matter

dark matterDark matter is something that has been on the minds of many scientists inclusive of astronomers ever since the theory of the evolution theory. It has sparkled the curiosity and imagination of many. There have been many suggestions about what dark matter is and this has brought about misunderstandings about how to define it. Some have termed dark matter to be a normal matter in the atmosphere and day to day life that cannot be seen while others have gone ahead and modified this and said it is something the naked eye and other apparatus such as the telescope cannot see. But we can today look at dark matter as an expansion of the universe. This dark matter is about 84% of the universe. Dark matter cannot be seen by the naked eye or scientific inventions. It doesn’t absorb light or energy in electromagnetic state. We can describe dark matter as a universe material that is there but is not seen to be there and the fact that we cannot see it does not mean we deny its existence.

The fact that dark matter is plentiful in the universe means that it interacts with human beings everyday. It is said that it interacts with an average person’s body approximately once every 60 seconds. Even now as people read this article, dark matter is busy bombarding with their body’s and they don’t it. Continue reading Ever Wondered What Is Dark Matter

Foods that taste good together – Is there any scientific co-relation?

foodThe art and science of wines, foods and flavor can be an intriguing issue to ponder over. The science of interrelation between food products is the major idea that Chartier Francois presents in his Taste Buds and Molecules book. Just like the title of the book suggests, the author looks at the aroma molecules which give wines and foods their definite character and taste. He uses the chemistry tied to foods as the major basis used for pairing wines and foods both. He goes ahead to propose the use of food charts to help in identifying the kind of foods which go well together. This is at least sheds some light on the science behind food compatibility and the reason why people need to grow over the past years of trial and error tastings. Continue reading Foods that taste good together – Is there any scientific co-relation?

Water on Mars

MarsWhile most of the scientific community believes that at one point, billions of years ago, there was water on Mars, it has been a difficult task to prove true. Two researchers at the University of Colorado at Boulder, Brian Hynek and Gaetano Di Achille have uncovered some new evidence that might shed light onto the subject.

While analyzing 52 different river deltas on the Martian surface, they discovered an interesting connection between 17 of them. Deltas are piles of sediment that form at the outlets of a river, similar to the one that the Mississippi River has been creating at the Gulf of Mexico. What Hynek and Achille have discovered is that 17 of the deltas on Mars are at a similar elevation within one standard deviation of each other, never straying more than 177 meters above or below the elevation they believe to be the surface of an ancient Martian ocean.

Do snake have ears?

SnakeWhenever we see snakes and when we notice their rapid movements there is one question that comes in our minds that whether snakes have ears or not? But this was one of the long-term myths that snakes are deaf and they cannot hear anything only the movement on the grounds can be sensed by them. But these points are no more exist able when it comes to rattle snakes where they can hear the rattling noise made by their tails.

A deep study has been carried out on this topic and analyses are made which proves that snakes do have internal ears and they can hear as well. Bruce Young is one of the neurobiologists and he made some new researches which can prove the mentioned points.

How humans inner ears are different from that of snakes? Human ears consists of several parts such as hair cells, bones and ear drum when there are sound waves that causes vibrations of tiny hair cells due to small movement of bones because of sound waves that hits the eardrum. These vibrations then reaches to the brain in the form of nerve impulses and this make us to hear the sounds. On the other hand snakes lacks these year drums and have totally different inner ear structures according to which their jawbone have a direct connection with their inner ears and the movements on the ground are received by their brain in the form of signals through their inner ears.
