Термін гіроскоп був запропонований в 1852 році французьким вченим Леоном Фуко. Він винайшов прилад, який демонстрував обертання Землі навколо своєї вісі. Постійно зростаючі вимоги до точнісних і експлутаційних характеристик гіроскопічних приладів стимулювали учених і інженерів багатьох країн світу не тільки до подальших удосконалень класичних гіроскопів з ротором, що обертався, але і до пошуків принципово нових ідей, що дозволяють вирішити проблему створення чутливих датчиків для індикації і вимірювання з великою точністю кутових рухів об'єкту в просторі. В даний час відомо більше ста різних явищ, і фізичних принципів, які дозволяють вирішувати гіроскопічні завдання.

Decision-making process
What type of decision-maker you are? Tick the statements that suit you the most and read the answers to this questionnaire at the end of the unit.
Type A
- You are a very decisive person, making quick decisions based on how you feel at the time. You like being in control of your decisions and are more likely to listen to your own feelings than to other people’s advice.
- You tend to take risks without really thinking through the long-term consequences.
Type B
- You tend to consider all your options carefully, weighing up the pros and cons. You have a strong sense of what you like and dislike, and know your strengths and weaknesses. Before making a decision, you find out as much information as you can, researching or asking people for advice.
- You also consider the long-term implications of your decision and rely on logic more than intuition. You take your time in deciding but one you’ve made up your mind, you will stick to it.
Type C
- You tend to be a cautious decision maker, not wanting to make mistakes or take unnecessary risks.
- You can see both sides of an argument and therefore know that each option has its good and bad points. This open-mindedness can be a good quality in terms of keeping your options open. However, it can also lead to confusion and may result in you not making decisions but letting events take over.
Type D
- In making your decisions, you consider other people’s feelings and actions. You are sensitive and like to avoid conflict. You like to be liked by others. Whilst this can be a good quality, you need to be careful that you are not influenced too much by other people.
- You tend to respond rather than lead and you prefer to be a member of a group rather than be on your own.
