It’s no secret that many of us are not too fond of mathematics and geometry, and that it is often too complex. But even so, it can be pretty mind-blowing to look back in history and discover the ...

It is important to remember other angles rules, such as angles on a straight line add up to 180°, and to recognise angles in parallel lines. Make sure you are confident in applying Pythagoras’ theorem ...

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

Abstract: We proposed a compact torsion sensor with high sensitivity using angle-offset long period grating (AO-LPG) inscribed in multicore fiber (MCF). AO-LPGs can be conveniently fabricated on the ...

Abstract: The conventional single-angle tilted fiber Bragg grating (TFBG) can only excite a certain range of cladding modes, limiting it for refractive index (RI) measurement in a wide range. In this ...

What is the secret behind Carl Schmitt’s contemporaneity and actuality? The argument relies on a broad endorsement of Schmitt’s interpretation of the age of the ius publicum—the body of maxims and ...
