Out of Time – Predicting the Science of Future Centuries and Millennia (Edition 2)

The universe is boundless and eternal, according to this text, but it was scientifically constructed. This contradiction of generating eternity is contingent on future humanity’s superior electronics. Time travel, as well as programmes that employ “imaginary” time and infinite numbers like pi, will be developed by those humans. They’ll also take on the names El […]

Basics of Nuclear Radiation

The first chapter of this book discusses nuclear radiation’s history, while the second and third chapters discuss nuclear radiation’s origins and forms. The X-ray was discussed in further depth in Chapter 4. Chapters five, six, and seven covered radiation amount, radiation interaction with matter, and radioisotopes, respectively. The usage and dangers of nuclear radiation on […]

On the Evolution of Universe Using Relativistic Cosmology

The geodesic equation is developed using calculus of variations for the collision region of two gravitationally coupled structures A and B. A method for calculating any conceivable curvature of universe beyond observable flat cosmos is discussed using the geodesic equation derived for the collision region of A and B. This relativistic method is used to […]

Application of Quantum Mechanical Calculations and Symmetry in Chemistry; Vibration Frequencies, Corrosion Inhibition and Prodrugs

The principles of nature are the sole foundation for ab initio quantum chemistry: Molecular modelling methods that can accurately predict structures, energetics, reactivity, and other features of molecules have been created over the last two decades. Computational chemistry does not replace experimental studies, but it does play an important role in chemists’ ability to: Many […]

The Uncertainty Principle: A Variable Concept. It Depends on the Complex Physical Time Only

According to the uncertainty principle, the quantity of uncertainty in a particle’s velocity multiplied by the quantity of uncertainty in a particle’s position is a constant. To put it another way, the more certain a particle’s velocity is, the less certain it is about its position, and vice versa. The focus of this chapter will […]

Symmetry between Shape and Orbit of Astronomical Bodies

In geometry, a sphere is the ideal shape. When enough mass clumps together to form an astronomical body, it tends to take the shape of a sphere. Any celestial body, regardless of its material composition, can achieve spherical form with a diameter of a few hundred kilometres. However, celestial bodies always deviate slightly from their […]

Trace Element Analysis of Dental Powders by X-Ray Fluorescence Technique: A Recent Study

The current study will focus on the experimental method, the elements that should be found in dental powder, and the findings. Medical research has shown that Hg is continuously emitted as vapour into oral air, inhaled, absorbed into body tissues, oxidised to ionic Hg, and finally covalently bonded to cell proteins throughout the last decade. […]

On the Design of a Yaw Colloidal Damper Used to Suppress the Hunting Motion and to Improve the Travelling Stability of a Bullet Train

The yaw damper is a primary source of excitation for the railway carbody’s flexural vibration. To decrease the transmission of such unwanted excitation, the yaw damper should allow for substantial force transmission at low working frequencies while acting as a vibration isolator at higher working frequencies. Unfortunately, the yaw oil damper, which is now in […]

Study on Thermomagnetic Conversion of Low-grade Waste Heat into Electrical Power

This chapter presents a theoretical analysis based on the thermal modelling of a Curie wheel, which is used to convert low-grade waste heat into electrical power. It enables designers to better understand the thermal behaviour of a Curie wheel in steady-state operation. A stationary one-dimensional analytical thermal model based on a Lagrangian technique was created […]

Multiple Geomatic Techniques for Analyzing Coastline Retreat: The Case of Gerra Beach (Cantabrian Coast, Spain)

Strong winter storms batter the beaches of the Cantabrian coast (northern Spain), causing the coastline to recede. The coastal retreat of the Gerra beach (Cantabria) is investigated in this chapter through a diachronic study using the following geomatic techniques: orthophotography from 1956; photogrammetric flights from 2001, 2005, 2010, 2014, and 2017; LiDAR survey from August […]
