Charles Hartshorne (1897–2000) was an American philosopher best known for his work in process philosophy and metaphysics, particularly in relation to the ideas of Alfred North Whitehead. Hartshorne's philosophy emphasized the dynamic and relational aspects of existence, positing that reality is characterized by change and that God is a being who is both in process and who interacts with the world.

David Bentley Hart is an American theologian, philosopher, and cultural commentator. Born in 1965, he is known for his work in the fields of religious studies, philosophy, and the interpretation of Christian theology. Hart has written extensively on a variety of topics, including metaphysics, ethics, and the nature of existence. He is particularly noted for his defense of Eastern Orthodox Christianity and his critiques of modern secularism and atheism.

Don Ihde is an American philosopher known for his work in the fields of philosophy of technology, phenomenology, and the philosophy of science. He is particularly noted for his contributions to the understanding of how technologies mediate human experiences and perceptions. Ihde's writings explore the relationship between humans and their technological environments, emphasizing the ways in which technology alters human experience and understanding.

BestCrypt is a software solution developed by Jetico Inc. that provides full disk encryption and file encryption capabilities. It is designed to secure sensitive data by encrypting entire disk partitions, virtual drives, or specific files and folders. BestCrypt offers strong encryption algorithms and features such as: 1. **Full Disk Encryption**: It can encrypt the entire operating system drive or other non-system drives to protect data from unauthorized access.

Perceptual computing refers to a field of computing that aims to enable machines to understand and interpret human sensory inputs, such as sight, sound, and speech, more naturally and intuitively. This involves creating systems that can perceive and respond to various forms of human expression, like gestures, touch, and voice, much like humans do in their interactions with each other.

Sequential logic is a type of digital logic circuit whose output depends not only on the current inputs but also on the history of past inputs. This means that the output state of a sequential logic circuit can change based on a sequence of inputs and the current state of the system. Unlike combinational logic, where the outputs are determined solely by the present inputs, sequential logic incorporates storage elements (memory), allowing it to maintain a state over time.

This is a good book, it gives a summary of biographies, and a reasonable description of the main ideas, with many illustrations. Each subject is not presented in incredible detail, but it is a good overview of events.

Mechanical fasteners are devices used to join two or more components together in a variety of applications. They provide a secure and stable connection while allowing for disassembly if necessary. Mechanical fasteners can be made from a variety of materials including metal, plastic, and composite materials and are used in a diverse range of industries, including construction, automotive, aerospace, and manufacturing.

The engineering design process is a systematic, iterative approach used by engineers to develop solutions to specific problems. This process typically consists of several stages that guide engineers from identifying a problem through to designing and testing a solution. While the exact steps can vary depending on the specific methodology, the following is a common sequence in the engineering design process: 1. **Define the Problem**: Clearly identify and articulate the problem that needs to be solved.

Backyard Ballistics typically refers to a DIY approach to creating and experimenting with small-scale projectile launching devices, often for educational and recreational purposes. It encompasses a variety of projects, including: 1. **Potato Cannons**: These devices use combustion or air pressure to launch potatoes or other small objects. 2. **Catapults and Slingshots**: Traditional mechanical devices that use tension or leverage to propel projectiles.

A bolt circle (or bolt circle diameter, BCD) is a term used in engineering and manufacturing to describe the diameter of an imaginary circle that passes through the centers of a set of evenly spaced bolt holes. It's commonly used in the context of wheels, flanges, and other components where bolts are used to attach parts together. The bolt circle measurement is important for ensuring that parts fit together properly and that the forces are distributed evenly across the connected components.

A centrifugal pendulum absorber is a type of vibration-damping device often used in machinery and automotive applications to mitigate torsional vibrations. It leverages the principles of centrifugal force and pendulum motion to absorb and dissipate vibrational energy. Here’s how it generally works and its key components: ### Working Principle: 1. **Basic Concept**: The device consists of a pendulum or a series of pendulums that are mounted on a rotating shaft.

"Chiller" can refer to different things depending on the context: 1. **Chiller (Cooling Device)**: In HVAC (heating, ventilation, and air conditioning), a chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. Chillers are commonly used in large buildings or industrial processes to cool water, which is then circulated through air handling units or other systems.

Reciprocating motion refers to the back-and-forth linear motion of an object between two points. This type of motion is characterized by the repetitive movement in one direction followed by a return in the opposite direction, creating a cyclic pattern. Common examples of reciprocating motion include: 1. **Pistons in an Engine**: In internal combustion engines, pistons move up and down within cylinders as a result of combustion pressure.

Constrained-layer damping (CLD) is a technique used to reduce vibrations and increase the damping of mechanical systems, particularly in structures like beams, plates, and automotive components. It involves applying a layer of viscoelastic material, sandwiched between a structural element (like a metal or composite layer) and a top layer that constrains the viscoelastic layer. The principle behind CLD is that the viscoelastic layer, when excited by vibrations, dissipates energy through internal friction.
