The world’s last dreadnought: Distinguished Lecture pays homage to Battleship Texas

Published by on in Distinguished Lectures
Reply

Ships named “Texas” have a grand history — just like the state. The first ship to bear the name came about when the United States realized it had less naval power than countries like Belize or Chile. The U.S. set out on a naval modernization program under the direction of then Undersecretary of the Navy Theodore Roosevelt, and built two modern battleships: the USS Texas (commissioned in 1895) and the USS Maine. 

While the Maine became infamous for starting the Spanish American War in 1898, the “Old Hoodoo” — as the Texas was called — under the command of Captain John “Jack” Phillips, served well at the Battle of Santiago de Cuba. There, she was part of Commodore Schley’s “Flying Squadron,” a force of ships gathered to defend the Atlantic coast against any Spanish fleets making their way to our shore. The Spanish fleet bottled up in the bay made a daring run to escape the blockading American fleet. In a matter of hours, the Spanish ships were sunk or run aground, and the U.S. fleet suffered only two casualties.

This first Texas was decommissioned in 1911 so her name could be added to a new dreadnought battleship, Hull No. 35. 

uss-texasLaunched on May 18, 1912, a few days after another infamous ship sank, the new Texas (BB -35) had a distinguished career with many firsts. Before she even had a shakedown cruise, she was off to support U.S. troops during the “Tampico Incident” in Mexico before World War I. Under the command of Victor Blue, she ferried convoys across the Atlantic and protected main layers around the northern German coast during World War I.  She escorted President Wilson to the peace conference after the war.  

During the intra-war years, she switched from burning coal to burning oil — a change that increased her range significantly and reduced the weight of the fuel she carried from 3,000 tons of coal to 400 tons of oil. She was the first battleship to have anti-air guns, launch a plane from her decks, and test radar. She participated in the landings in North Africa, the D-Day invasion, and the Battle of Okinawa, amongst others.

Since WWII, she’s been quite busy. In 1948, Texas became the first battleship memorial museum in the country. She currently serves as the flagship of the Third Texas Navy.

She also has an active acting career, playing the battleship West Virginia in Pearl Harbor. But I prefer when she plays herself in Letters from Iwo Jima and Flags of our Fathers. In the Ayes of Texas trilogy, she repeatedly saves the nation of Texas from the Soviet fleet. Way to go girl!

The next “Texas” was a Nuclear Guided Missile Cruiser (CGN). This Texas (CGN-39) was part of the new nuclear navy that launched in the 1960s and 1970s. She was second in the Virginia-class of cruisers. She participated in Operation Eagle Claw, an operation to rescue Iranian hostages. Under Captain William K. Gautier, she served as anti-air commander during the First Persian Gulf War. Due to the cost of maintenance and the fall of the Soviet Union, she was decommissioned about halfway through her expected life in 1993.

The current USS Texas has kept the nuclear tradition. She is second in the Virginia-class of nuclear attack submarines. Commissioned in 2004, the story of the USS Texas (SSN-775) is one shrouded by the depths of the sea. Under Commander Andrew Hertel, she patrols the ocean’s depths, looking for other silent and submerged killers, as well as surface fleets.

Join us on Tuesday, June 3 for our Distinguished Lecture Series to learn about the captains of the Battleship Texas and her place in history. The lecture is in conjunction with the showing of the incredible D-Day film and the Battleship Texas Centennial exhibit.

Digging in the dirt: Getting to know the Dimetrodon of the Texas Permian Red Beds

Published by on in Paleontology
1

I love my job. Not everyone can say that. My avocation and vocation are as two eyes with one sight (paraphrasing Robert Frost). Part of that job was taking a group of 15 patrons up to the Museum’s dig site outside Seymour, Texas. There, under the tutelage of Dr. Robert Bakker and David Temple, the group learned how to properly excavate bones of ancient animals —  in this case, Permian synapsids, amphibians, and fish.   

I got to go through a spoil pile (the pile of debris and castoff that others have thrown aside), and found several bits of our very early ancestors, the synapsid Dimetrodon.  I also worked on removing the overburden (the rock and dirt that is over a site we want to excavate), and found bits from a dorsal spine of a Xenacanthus, an ancient shark. It was the fulfillment of a childhood dream (as I child I played paleontologist rather than fireman and my first Deinonychus is still buried out back at my childhood home).

But I’m not the only one who dreamed of finding fossils in Texas.

Noted Swiss naturalist Jacob Boll came to Texas in 1869 to join La Reunion commune that is located in the current Reunion District of Dallas. (The Reunion Tower is named in honor of that small settlement.) La Reunion commune was responsible for the first brewery and butcher shop in the Dallas area. It also helped Dallas become the center for carriage and harness making.

Jacob Boll came over to set up high schools based in scientific inquiry. Through the late 1870s, he searched for fossils for Edward Drinker Cope, the noted “Bone Wars” paleontologist. Boll found over 30 new vertebrate species from the Permian period, which can be seen in the collections of the American Museum of Natural History.  Unfortunately, on his last trip, he was bitten by a rattlesnake, wrote some final letters to his family, composed a short poem in German, and died.  

In the Permian period, Texas was very different from today. Near Seymour, there were rivers and seasonal flood plains. However, even with this picture, there are still unexplained factors about the life of Dimetrodon — one being that there was not enough prey to sustain the population that we have found in the fossil record. While the Dimetrodon were making sushi out of Xenacanthus and chewing on some Trimerorhachis legs (like frog legs, only much shorter), there was not enough food to go around.

Now add to this case the curious fact that almost no Dimetrodon skeleton found has an intact tail. Anyone who has been to a good Cajun restaurant will know that the best meat on an alligator is the tail. And Dimetrodon would agree — hence the lack of tails.

But even this does not account for all the food necessary to keep all the predators alive.  Where is the missing food?

Dr. Bakker gave us a couple of hints as to what he thinks is the answer. 

 A few miles away from the site, there is an old Permian river basin where we find Edaphosaurus, a large Dimetrodon-like herbivore. Was it possible for Dimetrodon to walk a few miles, ambush an animal about its size, then walk back for a rest? This would provide food for the population.          

If you are interested in learning more about the Texas Red Beds, join us for our Fossil Recovery Class on May 20. You can go through some of our collection from the trip and learn about fossil collecting and identification techniques.

Science & The Simpsons, Part II: What does the future of energy hold?

Editor’s note: In our last post, we left off with Radioactive Man battling The Fossil Fuel Four, an episode of The Simpsons where the show personifies all major aspects for retrieving and releasing energy. Nuclear energy (fission) is represented by Radioactive Man, and his sidekicks Solar Citizen and Wind Lad represent solar and wind power respectively. In this episode, they face their nemeses: a rough group of villains who call themselves The Fossil Fuel Four. They’re made up of King Coal, Petroleumsaurus Rex, Charcoal Briquette, and the Fracker. Through their battle, we see the struggle between sustainable resources and fossil fuels.

Will climate change continue unabated? What will happen to Radioactive Man now as he battles The Fossil Fuel Four? Will he defeat his foes — or is it too late? 

The world’s first fission nuclear reactor was built in Chicago in 1942. Touted by scientists as the energy of the future, some believed that electricity produced in this manner would be so safe, plentiful and inexpensive that companies would no longer have to monitor usage.

But things haven’t quite panned out that way.

While there was a veritable boom in the construction of nuclear plants in the 1960s and 1970s, some very high profile setbacks (such as Chernobyl, Three Mile Island and Fukushima) have cast serious doubts about safety in the mind of the public. In response to Fukushima specifically, Germany intends to shut down all of its nuclear reactors within the decade, and Italy has banned nuclear power within its borders.

It remains, however, that nuclear energy has resulted in fewer deaths per unit of energy created than all other major sources of energy. Many scientists are still holding out hope for the development of nuclear fusion technology, which would be much more stable, secure, create more energy per unit, and not produce dangerous nuclear waste. This could be an economically viable option by 2050.

In the meantime, proponents of nuclear energy insist that the complete lack of carbon emissions from nuclear power plants should be a huge incentive for its use and maintain that it is a sustainable, safe method for the production of energy.

Additional sustainable energy options include solar and wind power (also hydropower, but since The Simpsons omitted it I will, in this case, refrain from delving into it further). Odd as it may seem, wind and solar power both capture energy from the same source – the sun. While solar power seeks to capture energy directly from the sun’s rays, wind power capitalizes on the fact that the sun’s energy heats the earth unevenly, creating wind currents (technically, even fossil fuels release energy from the sun, since that energy supported the life of the now fossilized organisms).

In the past few decades, these two processes of capturing energy and converting energy from the sun to electricity have grown by leaps and bounds. And while it’s still a small portion of total energy creation on a global scale, it seems to be one of the most promising ways in which we can create a truly sustainable energy environment for years to come.

Solar technology is generally categorized as either passive or active, depending on the method in which the sun’s energy is captured and converted for human use. Photovoltaic panels and solar thermal collectors are examples of active solar technology, while designing spaces to naturally circulate air and the selection of materials with light dispersing abilities are examples of passive solar technology.

Wind power uses airflows to run wind turbines. Harnessing wind for its energy has been a viable technology for millennia, but was (until recently) used to generate mechanical power (like using sails on ships), rather than electricity. As the wind blows, it turns the turbine to generate electricity. The greater the wind speed and strength, the more efficient this process becomes. This is part of why offshore turbines are becoming popular, since wind can be up to 90 percent stronger and occur more regularly out at sea than on land.

As you can see, this is a very exciting time for energy science with a lot of innovation going on. New technologies are being explored every day — from new methods of extracting fossil fuels from the Earth’s crust to new models and applications for nuclear, solar and wind energy production.

But the goal for all of this innovation is really the same: powering the future. So let’s revisit this idea of Radioactive Man and The Fossil Fuel Four.

Instead of The Fossils Fuel Four being evil, they and Radioactive Man should be the elders in the Energy League — a group of superheroes mentoring the new heroes in the league such as Citizen Solar, Wind Lad, Grid Smart, and Tidal Ti.  The Energy League should lead the fight against Baron Blackout and his cohorts, Social Disruption and the twins Ignorance and Want (OK, they’re Dickens characters, but wouldn’t they make great super-villains too?).

Let’s hope.

Science & The Simpsons, Part I: What’s a fossil fuel anyway?

When The Simpsons started in the late 1980s, very few people would’ve believed that the show could last as long as it has. Like the show or not, you can’t deny how it’s changed the way TV shows look at controversial material and incorporate current events and topics into their plots.

For instance, take Episode 450, “Married to the Blob,” which aired this past January. While the main story line deals with Comic Book Guy’s search for love, in quasi Much Ado About Nothing fashion, the first few minutes of the episode regale us with yet another adventure from the show’s favorite superhero, Radioactive Man.

And therein lies the show’s genius — what seems to be a short aside (an introduction at best) is actually an acute commentary on energy literacy: reflecting some of the struggles the industry faces as we seek to maintain energy independence, all while steadfastly moving into the future of energy production.

The show personifies all major aspects for retrieving and releasing energy. Nuclear energy (fission) is represented by Radioactive Man, and his sidekicks Solar Citizen and Wind Lad represent solar and wind power respectively. In this episode, they face their nemeses, a rough group of villains who call themselves The Fossil Fuel Four. They’re made up of King Coal, Petroleumsaurus Rex, Charcoal Briquette, and the Fracker (the names are likewise pretty opaque, with the characters representing coal, petroleum, charcoal, and the technique of fracking). Through their battle, we see the struggle between sustainable resources and fossil fuels.

It would be difficult to overstate the importance fossil fuels have had in creating the modern industrial world. The Industrial Revolution would’ve never occurred without ready access to coal, and the industrialized world still depends on it to a great extent. Fossil fuels have provided a ready source of energy for centuries now because they are easily burned to release their stored energy. When these fuels burn, they oxidize releasing carbon dioxide and water and produce large amounts of energy relative to their weight. These fuels can be found in solid, liquid and gaseous states (like coal, oil, and natural gas).

As these resources have become more scarce, new techniques have been developed to extract them from the earth, such as fracking (technically called hydraulic fracturing, which uses controlled explosions to break up the bedrock where these fuels are held) and surface mining (which removes vast amounts of surface rock to gain access to minerals).

Part of the reason why these new techniques have come into use is that fossil fuels are not easily or readily replenished. They are — quite literally — fossils, and therefore take a long time to form. (The word fossil simply means “evidence of past life.”) Over millions of years, tiny plants and other organisms would settle on the floor of a body of water (ocean, lake, etc.). Other sediment would settle over them, causing them to decompose in anoxic (read: with depleted oxygen) environments. After hundreds of millions of years of exposure to heat and pressure from added sediment, the organic matter is chemically altered. Depending on the type of organic matter, the amount of time and pressure applied, you get different types of fossil fuels.

It’s the depletion of fossil fuels and the negative consequences from them (such as poor air quality, which can lead to smog and acid rain, and the massive amounts of carbon dioxide released into the atmosphere, which has caused drastic changes in climate) that has led to our current quest for sustainable energy sources.

Editor’s note (Please read the following bold text in a cheesy, comic-announcer-type voice): Will climate change continue unabated? What will happen to Radioactive Man now as he battles The Fossil Fuel Four? Will he defeat his foes — or is it too late? 

Tune in next time as we catch up with our superhero.
