Summary
In 2013, a Boston Marathon bombing injured many. Dr. Jorge Alvarez responded to the emergency, running toward the danger to provide aid.
Area of Science:
- Emergency Medicine
- Trauma Surgery
- Public Health
Background:
- The 2013 Boston Marathon bombing involved two pressure-cooker bombs detonated near the finish line.
- The attack resulted in three fatalities and hundreds of injuries.
Purpose of the Study:
- To describe the immediate response to the Boston Marathon bombing.
- To highlight the actions of medical professionals during a mass casualty event.
Main Methods:
- Qualitative description of the event and immediate aftermath.
- Personal account of a physician's response.
Main Results:
- Dr. Jorge Alvarez, an emergency physician, immediately ran toward the explosion site.
- The response involved immediate on-site medical care and triage.
Conclusions:
- Physicians and other medical personnel often act heroically in mass casualty incidents.
- Rapid response is critical in mitigating casualties during terrorist attacks.

Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...

44.7K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:48Classification of Skeletal Muscle Fibers
59.5K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

02:04Conservation of Small Populations
17.1K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

02:39Gibbs Free Energy
38.5K
One of the challenges of using the second law of thermodynamics to determine if a process is spontaneous is that it requires measurements of the entropy change for the system and the entropy change for the surroundings. An alternative approach involving a new thermodynamic property defined in terms of system properties only was introduced in the late nineteenth century by American mathematician Josiah Willard Gibbs. This new property is called the Gibbs free energy (G) (or simply the free...
