Compass points, angular markings. Travel Tips

Tourist tips

Sailors of the past marked their compasses with the so-called main compasses. points - north (N), south (S), east (E) and west (W) - and quarter points - northeast (NE), southeast (SE), southwest (SW) and northwest ( NW), dividing the compass card into 45° segments.

A more fractional division into north-north-east (NNE), east-north-east (ENE), east-south-east (ESE), south-south-east (SSE), etc. is also used. There is even more fine division of the limb, in particular into north-shadow-east (NxE), with a mark between N and NNE and north-east-shadow-north (NExE) with a mark between NNE and NE. In total there are 32 compass points with an angle of 11,25° between them. These days, all of them are rarely used, usually to indicate the general direction of movement.

Angular layout

The limbs of modern compasses have marks of angular degrees from 000 to 359 °, as well as the main points N, S, E and W. The compasses with a substrate used by tourists usually have marks arranged in a circle with a discharge of 2 °; reflective prism compasses and hand compasses are more accurate and contain a mark for every degree and even half a degree. Steering compasses with marks every 5° are not used to determine bearings.

Compass bearings and courses defined in degrees are usually expressed in three digits, even if their value is less than 100°. For example, east is 090° and northeast is 045°.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Sunlight increases the sexual activity of men 07.10.2016

Scientists at the European University Neuropsychopharmacological Congress found that a daily dose of bright light can increase testosterone levels, increasing male potency and sexual activity.

The researchers recruited 38 male subjects who were diagnosed with a disorder characterized by a lack of interest in sex. Their baseline libido and testosterone levels were measured prior to the start of the trial, after which the subjects were divided into 2 groups: one received a 30-minute "shower" of white fluorescent light at an intensity of 10,000 lux immediately after waking up, and the control group received a placebo in a much less intense light.

Before starting the treatment program, the men rated their sexual satisfaction at 2 points out of 10. After two weeks, those who regularly received a dose of bright light had a three-fold increase in libido, and patients already rated it at 6 out of 10. In the placebo group, however, only a sluggish increase to 2,7 was observed. The level of testosterone in the first group also increased from 2,1 ng / ml to 3,6 ng / ml, which also served as an incentive to increase sexual activity.

“In the Northern Hemisphere, testosterone production naturally declines between November and April, and then gradually rises during the spring and reaches its peak in the summer. Simulation of the sunny season really plays a big role in a person’s sex life: you can see that most often the reproductive surge is observed in June-July," notes Andrea Fagiolini, lead scientist and author of the study.

According to experts, phototherapy may be more effective than taking antidepressants or chemical injections of pathogens, while it does not cause side effects. For both men and women experiencing various problems associated with sexual dysfunction, such therapy will only benefit.
