Edwin Hubble’s Birthday – Quote on Positive Science

Edwin Hubble was born on this day in 1889. He would go on to become an accomplished astronomer who made crucial contributions to extra-galactic astronomy and cosmology. He showed that galaxies further from Earth were receding away from us faster than closer galaxies, which implied that our universe is expanding.
The Hubble Space Telescope was named in his honor.

Galileo Vs Authority Design and Sale

Galileo was all too familiar with what can happen when reason and evidence are suppressed by authorities who want to control our perceptions of truth. Science cannot truly flourish and real progress cannot be made unless such authorities are challenged when they stand in the way. This design celebrating Galileo’s achievements and his rebellious nature is one of many available in our online store. Everything is now on sale to commemorate the anniversary of his sentencing —> http://punkrockscientist.storenvy.com/

And if you’d like to learn more about Galileo’s discoveries and his scientific drawings (some of which are featured in this design) then check out this post.

Science News – June 3rd, 2016

Science News! Let’s take a look at some of the important developments in science this week…

First, X-ray fluorescence spectrometry has revealed that a dagger found in the tomb of King Tut was made from a meteorite. The blade has resisted rust and age and its origin had been a puzzle until now. Read more from the Smithsonian here.

Second, scientists have outlined a plan to create an entire synthetic human genome in the lab. This could lead to medical breakthroughs, but it raises many concerns and would be a daunting task. Read more from NPR here.

Third, the Hubble telescope has taken measurements that conflict with studies of the left over radiation from the Big Bang, and show the Universe is expanding 5 to 9% faster than previously thought. The reason for the discrepancy is not yet known but may have something to do with unknown subatomic particles or with dark energy. Read more from the Guardian here.

Science News – May 27th, 2016

Science News! Let’s take a look at some of the important developments in science this week…

First, scientists entered the Bruniquel Cave in southern France, which had been sealed off for thousands of years, and found mysterious semicircles of stalagmites and evidence of fires that had been created by Neanderthals. Uranium dating shows the rings were stacked up 175,000 years ago, which makes them among the oldest structures created by our human relatives ever found. What the purpose of the structures was is still a mystery. Do you have a theory? Read more from the Smithsonian here.

Second, astronomers using the world’s most powerful telescope and a gravitational lensing technique were able to detect the faintest galaxy of the early universe yet found. The galaxy was born just after the Big Bang and appears to us as it was 13 Billion years ago. Read more from Phys.org here.

Third, the American military has reported the first instance of a bacteria resistant to colistin, a drug considered the last resort in killing superbugs. Although resistant to this last resort drug, the bacteria in this case was luckily not resistant to a class of drugs called carbapenems, and the patient who was carrying the bacteria is now well. However, if bacteria that are resistant to carbapenems are also able to acquire the resistance to colistin they may be unstoppable. Read more from the New York Times here.

Design Release – Galileo on Science and Authority

New design! After his works were banned and he was labeled a heretic for presenting evidence that the planets orbit the sun and not the earth, Galileo was fully aware of the power of authority to suppress science. This design features a quote from Galileo on the subject, as well as sketches he made of the moon and stars, a replica of his telescope, and a recreation of his sketches of Jupiter and its orbiting moons.

Available now in our online store!

Five Awesome Images from Galileo’s Works

Galileo improved upon the rudimentary telescopes of his day, creating instruments which allowed him to see the objects of outer space with greater clarity than anyone before him. He made careful observations and drew meticulous sketches to document what he saw. Despite the fact that he was labeled a heretic for believing that his observations show the earth is not the center of the universe, and despite the fact that his works were not fully released from the Catholic Church’s ban until 1835, his amazing words and illustrations survived. Here are a few examples of his accomplishments…

Observations of the Moon

Galileo Moon Sketches

In Galileo’s time it was believed that the heavenly bodies were all perfectly created spheres, that could not have their own orbiting moons, or any mountains, craters, or other features that would mar their perfection. When Galileo looked at the moon through his telescope he was able to see that the moon clearly has many mountains and craters and was definitely not a perfectly smooth sphere. He made detailed sketches of what he saw, part of the evidence that led him to believe that the other planets are not perfect spheres orbiting the earth as others believed in his day.

Sketches of the Phases of Venus

Galileo Phases of Venus

Galileo observed that the planet Venus goes through phases over time, just like the moon. This would only happen if the planets orbited the sun, and not the earth. These observations provided strong evidence that the geocentric model of the solar system was not correct. Despite this and other evidence, Galileo’s belief in the heliocentric model still ended up being labeled as heretical.

Sketches of Sun Spots

Galileo Sun Spots

Galileo created meticulous drawings of the movement of sunspots over time, showing how they traveled across the face of the sun and would seem to appear and disappear. Others had argued that sunspots were simply the planet Mercury crossing in front of the sun, or bodies orbiting the sun. Galileo argued that sunspots were more like clouds on the surface of the sun, something which contradicted the prevailing view of the perfect and unchanging heavenly bodies.

Observations of the Moons of Jupiter

Galileo Jupiter Moons

When Galileo looked at Jupiter through his telescope, he observed small points of light around it that he first thought were stars. He noticed however, that the lights appeared at different positions through time. Galileo created simple sketches representing Jupiter with a circle, and the lights as asterisks. He showed that the lights must be moons orbiting Jupiter, something that many were unwilling to believe, because it was thought that only the earth could have orbiting bodies.

Sketches of the Pleiades Constellation

Galileo Pleiades

Galileo studied the stars and the Milky Way and the constellations that were known in his time. He found that there were many more stars visible with a telescope than could be seen with the naked eye. Galileo was seeing stars that no one had seen before, and he recorded his observations with beautiful sketches.

Galileo’s works would eventually help to change our views on the nature of the universe and our place within it. Thankfully, despite the censorship imposed on his ideas, his works are still here for us to enjoy and learn from today.

Science Quote – Galileo on Improbable Facts and Simple Beauty

Many people find the realities that science reveals improbable. They believe that the big bang, evolution, climate change, or other events sound too far fetched to be true.

But what about water? We are used to seeing water change from liquid to ice or to steam, and yet this would seem like magic if we had never witnessed it before. The explanation can be reduced to the simple understanding that water is made of molecules, and that energy can break the connections between the molecules, causing them to spread farther apart.

Similarly, it is not difficult to understand that the many successive layers of rock laid down on earth show that it is very old. Or that animals pass down traits to their offspring, and those that inherit better traits for survival will have more offspring of their own compared to their peers. Put a few such simple facts together, and evolution no longer seems so improbable.

Science is not just a jumble of confusing mathematics and terminology. It is not beyond the grasp of the average person’s understanding. Although at its deeper levels it can be bewildering, it is also capable of providing beautifully simple explanations for the mysteries of the world, something that Galileo realized hundreds of years ago.
