The computing power of the Mercury spacecraft compared to a modern iPhone is starkly different, highlighting the vast technological advancements over the past decades.

Mercury Spacecraft (1959-1963):

- The Mercury spacecraft's computing capabilities were minimal. The onboard systems were primarily mechanical and analogue, with minimal digital computation. Most calculations were done on the ground, and communication with the spacecraft was handled through radio telemetry.

- The only real "computer" involved was the ground-based IBM 701 or 7090, which handled data processing and flight simulation.

- The onboard systems mainly relied on simple transistor-based electronics for control and navigation, with computation power measured in just a few thousand instructions per second (KIPS).

Modern iPhone (e.g., iPhone 14 Pro):

- A modern iPhone has a multi-core processor with billions of transistors and can perform up to trillions of operations per second (teraflops). For instance, the A16 Bionic chip can handle up to 15.8 trillion operations per second.

- The iPhone also includes advanced graphics processing units (GPUs), neural engines for AI and machine learning tasks, and substantial amounts of RAM and storage.

Comparison:

The Mercury spacecraft's computing power is dwarfed by that of a modern iPhone, which is millions of times more powerful in terms of computational capability.

- To put it in perspective, the iPhone in your pocket has more computing power than all of NASA's computers combined at the time of the Apollo moon landings, let alone the Mercury missions.

- The iPhone can perform complex computations, support high-resolution graphics, and manage extensive communication and data processing tasks that would have been unimaginable with the technology available during the Mercury program.

In essence, the Mercury spacecraft had the equivalent of almost no digital computing power compared to the highly advanced and capable iPhone of today.

Two U.S. Presidents are buried at Arlington National Cemetery:

John F. Kennedy - The 35th President of the United States, assassinated in 1963, is buried in Arlington. His gravesite is marked by an eternal flame and is one of the most visited spots in the cemetery.

William Howard Taft - The 27th President of the United States, who also served as Chief Justice of the Supreme Court, is the other President buried at Arlington. Taft died in 1930, and his grave is less elaborate compared to Kennedy's but still a significant historical site within the cemetery.

The last ex-president to drive across the country was Harry S. Truman. After leaving the White House in January 1953, Truman and his wife, Bess, embarked on a road trip across the United States. The journey began in Independence, Missouri, and spanned 19 days, covering over 2,500 miles.

Truman's road trip was quite a significant event, as it was unusual for a former president to travel in such an unassuming manner. The Trumans traveled without Secret Service protection, which was not mandatory at the time, and drove their own car, a Chrysler New Yorker. They stayed in motels and visited friends along the way, drawing attention and admiration from the public wherever they went.

This journey is well-documented in Matthew Algeo's book Harry Truman’s Excellent Adventure: The True Story of a Great American Road Trip, which provides a detailed account of the trip and its significance in American history.

• “Four years ago, lying opponents said the country was tired of its ideals - they waged a campaign based on an appeal to prejudice based on the dragging out of bogies and hobgoblins, the subtle encouragement of false fears. America has not lost her faith in ideals - idealism is her heart’s blood. Tricked once we have been.
  
  - Millions of voters are waiting today for the opportunity next November to reveal their vengeance on those deceivers. They await the opportunity to support a man who will return America to the fold of decency and ideals from which she has strayed and who will bring the Government back to the people.”
  
  - FDR’s nominating speech at the 1924 Democratic Convention in support of Alfred E. Smith, Governor of New York.
  Roosevelt didn’t want to give the speech, having written one himself. Al Smith insisted. Roosevelt relented and delivered the speech to thunderous applause. It was the first time Roosevelt delivered a public speech after contracting polio in 1921.

The ability for individuals to directly vote for U.S. Senators was established by the 17th Amendment to the Constitution, which was ratified on April 8, 1913.

Before the 17th Amendment:

- State Legislatures' Role: Prior to the 17th Amendment, U.S. Senators were elected by state legislatures, not by the general public. This process was outlined in Article I, Section 3 of the U.S. Constitution.

After the 17th Amendment:

- Direct Election: The 17th Amendment changed the process so that Senators would be directly elected by the people of each state. This shift was made to make the Senate more responsive to the public and to reduce corruption and political manipulation that had occurred under the legislative election system.

Since 1913, U.S. citizens in each state have had the right to vote directly for their Senators.

The Bull Moose Party, officially known as the Progressive Party, was a political party in the United States formed by former President Theodore Roosevelt in 1912 after a split within the Republican Party. Here's what happened to the Bull Moose Party:

Formation and 1912 Election

- Origins: The Bull Moose Party was born from a rift between Theodore Roosevelt and the sitting President, William Howard Taft. Roosevelt, who had served as president from 1901 to 1909, was dissatisfied with Taft's conservative policies and decided to challenge him for the Republican nomination in 1912. When Taft won the nomination, Roosevelt and his supporters broke away to form the Progressive Party.

- The Bull Moose Party, affectionately nicknamed after Roosevelt's assertion that he felt 'as strong as a bull moose,' was a beacon of progressive reforms. It championed causes such as women's suffrage, social welfare programs, workers' rights, and the regulation of big businesses, demonstrating a strong commitment to change and reform.

- In the 1912 presidential election, Roosevelt ran as the Bull Moose candidate. His exceptional performance, securing 27% of the popular vote and finishing second behind Democrat Woodrow Wilson, was one of the best by a third-party candidate in U.S. history. However, it split the Republican vote, ultimately allowing Wilson to win the presidency, a testament to the Bull Moose Party's significant impact on U.S. history.

Decline and Dissolution

- Post-1912: After the 1912 election, the Bull Moose Party quickly lost momentum. Many of its supporters, who were originally Republicans, started to drift back to the Republican Party. The party needed the unifying figure of Roosevelt to maintain its relevance, who was the central force behind its creation.

1916 Election: In 1916, the Bull Moose Party attempted to mount another presidential campaign. However, Roosevelt declined to run and instead endorsed the Republican candidate, Charles Evans Hughes. Without Roosevelt's leadership, the party failed to gain significant support and effectively dissolved.

- Legacy: By the end of 1916, the Bull Moose Party had largely ceased to exist as an organised political force. However, its legacy lived on in the progressive policies it championed, many of which would later be adopted by the Democratic Party during the New Deal era under Franklin D. Roosevelt.
