Neil Postman on Science

Neil Postman in his essay, “Science and the Story We Need,” has this to say, “But in the end, science does not provide the answers most of us require. Its story of our origins and of our end is, to say the least, unsatisfactory. To the question, “How did it all begin?”, science answers, “Probably by…

Saturn’s Polar Vortex

Cassini has begun grazing the rings of Saturn. This represents the next phase in the journey of NASA’s preeminent spacecraft. Around November 30, 2016, Cassini began orbits that swing close to the outer rings and give a great view of the north pole of the gas giant. The resulting images are spectacular and are a…

CRISPR

CRISPR is a relatively new term that describes new discoveries and new technology in the world of genetics. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats and refers to short repetitions of base pair sequences in bacterial genomes which naturally occur as part of bacterial genetic defence mechanisms against invading viruses. These CRISPR sequences…

Cassini

Recently I wrote a sad lament for the Schiaparelli Lander, even as I praised those who had successfully inserted the Trace Gas Orbiter (TGO) into a near-perfect orbit around Mars. This orbiting communications relay and atmospheric laboratory will serve NASA scientists for the next several years and will eventually support a European Space Agency (ESA)…

Mysteries of the Human Genome

Many who read this blog regularly will know of my interest in human genetics and the evolutionary process by which God guided the creation of humans and imprinted the imago dei upon us. I have frequently written about various creation and evolutionary theories and I recognize that this is a controversial topic in some Christian…

A Robotic Spacecraft Dies

This week was supposed to be a week of good news for the Schiaparelli lander. It was expected that by this time, the Trace Gas Orbiter (TGO) would be relaying information from Schiaparelli to Earth and science experiments would be about to begin on the surface of Mars. The European Space Agency (ESA) did have…

Animal Intelligence

I am fascinated by the intelligence of animals. On the farm where I grew up, we often had Border Collie dogs who were intelligent working dogs. They were exceptional herders and one dog was capable of finding the milk cows in the field and herding them into the barnyard on his own. Our daughter and…

Schiaparelli

(Click on this thumbnail picture for a larger image.) This week in solar system navigation, the Schiaparelli Lander was given the necessary software to allow it to land on Mars. Descent and soft touchdown on Mars will be guided by the commands that were uploaded on October 7th. The fact that such commands can be…

Thermophilic Bacteria as Great Wonders of the World

Lewis Thomas[1] was an award winning author and physician who had a way of explaining complex science in simple ways. In his essay, “Seven Wonders[2],” Lewis relates how he was once asked for his list of contemporary “Wonders of the World.” He is careful to say that he thinks it would be impossible to create…

There is Nothing to Match it Anywhere

Perhaps as a follow-up to my post of a few days ago, these words of the great science writer, Lewis Thomas would be appropriate. Of all celestial bodies within reach or view, as far as we can see, out to the edge, the most wonderful and marvelous and mysterious is turning out to be our…
