Q & A
What wiped out the dinosaurs 66 million years ago?
-An asteroid impact in the Gulf of Mexico wiped out the dinosaurs 66 million years ago. The asteroid was over 7 miles wide and created a crater 120 miles wide in the Gulf.
How did the asteroid impact lead to global extinction?
-The asteroid impact vaporized sulfur-rich rocks and ejected them into the atmosphere, blocking sunlight and cooling the planet. This disrupted the food chain, leading to mass extinction.
What was the economic impact of the Deepwater Horizon oil spill?
-The Deepwater Horizon oil spill in 2010 was the largest marine oil spill in history. Over 4 million barrels of oil poured into the Gulf of Mexico, devastating tourism and fishing industries.
How did the Germans exploit American vulnerability in WWII?
-At the start of WWII, American coastal shipping was vulnerable to German U-boats. The U.S. failed to impose a coastal blackout, allowing U-boats to easily spot and sink ships.
What were privateers and how did they operate?
-Privateers were privately owned ships authorized by governments to attack enemy shipping. Many operated in the Gulf of Mexico in the early 1800s.
What was the slave trade like in the Gulf of Mexico?
-The Gulf of Mexico was a major route for the illegal slave trade in the early 1800s after it was banned. Captured Africans were smuggled through the Gulf to slave markets.
How was oil first extracted in the Gulf?
-In the 1940s, companies discovered that oil flows naturally from reservoirs beneath the Gulf's shallow continental shelf, enabling productive offshore drilling.
Why did the Deepwater Horizon explosion happen?
-The cement designed to seal the exploratory Macondo well failed, allowing gas under high pressure to reach the rig and ignite.
What were German U-boats doing in the Gulf of Mexico in WWII?
-Germany sent U-boats to sink merchant shipping in the Gulf of Mexico to disrupt the oil supply and Allied war effort.
How was the U-166 sunk?
-After torpedoing the Robert E. Lee, U-166 was sunk by depth charges from an American submarine chaser in July 1942.
Outlines
🔴 Dinosaurs wiped out by asteroid strike in Gulf of Mexico
An asteroid over 7 miles wide struck the Gulf of Mexico 66 million years ago, creating a 120 mile wide crater. It released energy equal to 10 billion nuclear bombs, sending vaporized rock into the atmosphere which blocked sunlight, cooled the planet, and wiped out 75% of life including the dinosaurs.
🛢️ Perfect conditions for oil formation in Gulf of Mexico
300 million years ago the Gulf of Mexico was an ancient swamp. Pressure and heat transformed the organic material into oil. The geology of the Gulf provides perfect conditions for offshore oil drilling - shallow continental shelf, oil-rich source rock, and impermeable cap rock to trap the oil.
💥 Deepwater Horizon disaster - unsafe drilling practices
The Deepwater Horizon was drilling an exploratory oil well 50 miles offshore when improper cementing led to a blowout. Oil erupted onto the rig, causing an explosion. It took 87 days to cap the damaged wellhead, spilling nearly 5 million barrels of oil in the worst environmental disaster ever in the Gulf.
🏴☠️ Sunken ships reveal Gulf's pirate history
Advanced scanning technology reveals shipwrecks in the Gulf, providing insight into the 19th century history of piracy and slave trade. One wreck may have been a merchant ship protected by a privateer. Hundreds of ships moved through the ports, both legally and illegally.
🚢 U-166 sunk by US patrol boat in WWII
German U-166 was on patrol in 1942 when it torpedoed an American passenger freighter. It was then depth charged by a US patrol craft in a deadly duel. The U-Boat lies 2 miles from the freighter wreck, its bow blown off by the explosions.

Highlights
Proposed a new deep learning architecture called Transformers that relies entirely on attention mechanisms without RNNs or CNNs.
Showed that attention can be used to draw global dependencies between input and output in neural sequence transduction models.
Demonstrated that Transformers outperform RNN/CNN models like LSTM/ResNet on machine translation tasks while being more parallelizable and requiring less computation.
Introduced multi-headed self-attention where a model learns attention from different representation subspaces at different positions.
Proposed masking future positions during training so that a model only attends to previous positions in the input sequence.
Achieved state-of-the-art results on English-to-German and English-to-French translation datasets with the Transformer model.
Showed that attention weights can be interpreted as an alignment between input and output sequences.
Demonstrated that residual connections between layers in conjunction with layer normalization stabilize the training of deep Transformers.
Highlighted that Transformers are more parallelizable than RNNs, allowing significantly more computational efficiency.
Discussed how self-attention draws global dependencies in the input and output sequences.
Noted that Transformers can model longer-range dependencies than RNNs and CNNs.
Suggested that the Transformer architecture has the potential to become the dominant sequence transduction model.
Emphasized the flexibility of self-attention to attend to different positions based on the query, unlike RNNs.
Observed that Transformers strongly outperform RNNs on tasks with long-range dependencies.
Concluded that attention-based models surpass RNN/CNN models on machine translation and have broader applications.
