Sadly, the designs were later changed, much to Andrews' unhappiness with the bulkheads being installed much shorter to allow more deck and storage space above. They also reduced the number of lifeboats required. These changes to Andrew's STEM calculations led to Titanic's demise and great loss of life on April 14 1912.

That night it struck an iceberg. Water flooded through the bulkheads. Andrews' bulkhead gates were closed but the reduced depth of the gates meant water poured over the top of each compartment tipping the ship's bow deep into the water. The weight of water would then take the ship down into the murky depths of the cold Atlantic Ocean. 

Andrews, who was on board the ship at the time, told the Captain that when five of the compartments had flooded it was a 'mathematical certainty' that the ship would sink. It certainly did. The science involved taking over 1500 people to their deaths. This total included Thomas Andrews.  You see how important STEM is? Science, Technology, Engineering & Maths can save or lose lives.
