6 of the Longest Experiments Ever

The video explores some of the world's longest-running scientific experiments, including the Oxford Electric Bell, Beal Seed Experiment, Pitch Drop Experiment, Framingham Heart Study, Lenski's E. coli Experiment, and the 500-Year Microbiology Experiment. These experiments provide insights into various scientific phenomena, from battery longevity and seed viability to viscosity, cardiovascular health, bacterial evolution, and microbial survival. Each experiment offers unique contributions to scientific knowledge, demonstrating the value of long-term research.

What is unique about the Oxford Electric Bell experiment?

• It uses a liquid electrolyte.

• It is powered by solar energy.

• It was invented in the 20th century.

• It has been running for over 177 years.

What was the original purpose of the Beal Seed Experiment?

• To test new agricultural techniques.

• To develop new species of plants.

• To determine how long seeds can remain viable in soil.

• To study the effects of climate change on seeds.

How often are the bottles in the Beal Seed Experiment currently being unearthed?

• Every 5 years

• Every 20 years

• Every 10 years

• Every 50 years

What does the Pitch Drop Experiment demonstrate?

• The flow of pitch, a substance that appears solid.

• The solidification of liquids over time.

• The effects of temperature on viscosity.

• The evaporation rate of liquids.

Why was the Pitch Drop Experiment almost discontinued in the 1980s?

• The experiment was deemed unnecessary.

• The equipment was damaged.

• The university ran out of funding.

• The pitch had stopped flowing.

What significant health factors were linked to heart disease in the Framingham Heart Study?

• Diet and exercise

• Cholesterol and high blood pressure

• Genetics and age

• Stress and sleep patterns

What was a key finding from Richard Lensky's E. coli experiment?

• E. coli became resistant to antibiotics.

• E. coli can photosynthesize.

• E. coli evolved to digest citrate.

• E. coli can survive without oxygen.

What is the main goal of the 500 Year Microbiology Experiment?

• To develop new antibiotics.

• To understand microbial survival in extreme conditions.

• To observe microbial evolution over centuries.

• To study the effects of radiation on microbes.

How often will the vials in the 500 Year Microbiology Experiment be opened starting in 2038?

• Every 25 years

• Every 10 years

• Every 5 years

• Every 50 years

What additional purpose do the vials in the 500 Year Microbiology Experiment serve?

• They are used to test new preservation techniques.

• They act as a time capsule of microbial life.

• They help in developing new microbial species.

• They are a backup for future experiments.
