Accelerators01:17

Accelerators

279
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.
The effectiveness of calcium chloride can...

Accelerating Fluids

2.3K
When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

Instantaneous Acceleration01:16

Instantaneous Acceleration

22.8K
Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...

Acceleration Vectors

In everyday conversation, accelerating means speeding up. Acceleration is a vector in the same direction as the change in velocity, Δv, therefore the greater the acceleration, the greater the change in velocity over a given time. Since velocity is a vector, it can change in magnitude, direction, or both. Thus acceleration is a change in speed or direction, or both. For example, if a runner traveling at 10 km/h due east slows to a stop, reverses direction, and continues their run at 10 km/h...

Average Acceleration

The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...

Measuring Acceleration Due to Gravity

1.2K
Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die out.
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

Summary

Cultural trends are accelerating, with popular topics gaining and losing attention faster than ever. This study models how increased content drives rapid attention shifts and shorter lifespans for cultural items.

Area of Science:

  • Sociology
  • Information Science
  • Media Studies

Background:

  • Modern information dissemination, via smartphones and social media, creates rapid, fragmented public discourse.
  • Longitudinal data reveal increasing gradients and shortened attention spans for cultural items over decades.

Purpose of the Study:

  • To investigate if accelerated information consumption inevitably leads to fragmented public discussion.
  • To model the dynamics of collective attention to cultural items.

Main Methods:

  • Analysis of longitudinal datasets across diverse domains spanning multiple decades.
  • Development of a mathematical model simulating competition for finite collective attention.

Main Results:

  • Empirical data on cultural attention trajectories are well-explained by the mathematical model.
  • Increased content production and consumption lead to faster exhaustion of limited attention resources.
  • Competition for novelty exacerbates rapid turnover and shortens the collective attention period for individual topics.

Conclusions:

  • The observed acceleration and fragmentation of public discussion are likely inevitable outcomes of current information dissemination and consumption patterns.
  • Finite collective attention resources are rapidly depleted by increasing content volume and the drive for novelty.
  • This dynamic results in shorter lifecycles for popular cultural items.
