Auto insurance can include a wide range of coverage, from liability-only to coverage that will fix the smallest dent or scratch on your car's paint job. With auto insurance being required by law in many places, you may be confused as to what kind of coverage you need. This article will explain the basics and help you learn what you need to know about car insurance. Being a careful driver can really save you money on insurance. Obviously, insurers would rather insure good drivers and will provide lower rates for good drivers, but did you know that causing an accident can make your insurance rates nearly double? It is abundantly clear that driving safely is one of the best ways to keep your insurance rates low! To get the most for your money when pricing automobile insurance, be sure to consider the extras that are included with some policies. You can save on towing costs with emergency roadside assistance that is included by some insurers. Others may offer discounts for good drivers or including more than one car on your policy. A simple way to save a bit of money on your auto insurance, is to find out whether the insurance company gives discounts for either paying the entire premium at once (most will give you a small discount for doing this) or taking payments electronically. Either way, you will pay less than shelling out each month's payment separately. One of the best ways to get great deals on automobile insurance is to speak to someone in person or at least on the phone. Insurance is automated and very easy to get online, but actually speaking with someone allows for the back-and-forth Q "�n' A session that may introduce you to some discounts you did not previously know about. It is vital that when making an automobile accident claim, that you have all the information available for the insurance company. Without it, your claim may not go through. Some things you need to have ready for them include the make and year of the car you got into an accident with, how many people were in each car, what kinds of injuries were sustained, and where and when it happened. Know different coverage options, and check to be sure your insurance provides the best coverage. Liability is important both for damage you cause to other people, and damage you cause to yourself or your own property. Other types of coverage that you need include protection from uninsured drivers and damage from fire or other disasters. With many insurance companies, teenagers have to pay more for auto insurance. This is because they are considered to be high risk drivers. In order to make auto insurance more affordable for teenagers, it may be wise to put them on the same insurance as a more experienced drive, such as their mother or father. You might be able to save on auto insurance by obtaining a bundled insurance package. Search for these types of offers, especially those that bundle auto and homeowners insurance. Ensure you are paying an affordable rate for good coverage as sometimes two sets of insurance is the better option. Write down a list of each discount your insurance company offers. Go through that list and put a check mark next to any that apply to you. You might be surprised at how much you can save by claiming discounts. If you want to avoid paying a high premium, don't drive a flashy car. Sports cars and other high performance vehicles, often have premiums that are two or three times larger than that of a standard car. You should also research commonly stolen vehicles and be sure to avoid them. Most insurance companies will charge significantly more to insure these types of cars. When you go hunting for car insurance bargains, do not neglect your employer as a potential source of discounts. Many companies - even relatively small ones - have arrangements with insurers to get volume discounts for their employees. If your employer has such a program in place, you might realize significant savings by taking advantage of it. To ensure you continue to get the best possible car insurance, it is wise to do a little comparison shopping against your current policy from time to time. Doing this about a month before your policy renews is a great strategy. This allows you to take advantage of a better offer or use it to negotiate a new rate with your current insurer. When trying to get affordable auto insurance, keep in mind your state's minimum liability coverage requirements. You need to know what minimums to obtain so that you can get a policy that matches these particular minimums. You can find a list of your state's minimums at your state's insurance commissioner's website. Consider switching your current insurance to a lower coverage policy to save a few more dollars. Depending on your state's insurance requirements and if you are leasing or renting to own a vehicle, you may be able to lower your insurance coverage to save a little extra money each month. If you finance your vehicle, your lender may have requirements governing the level of auto insurance you must maintain during the duration of the loan. Generally, the requirements relate to how high you can have your deductible. Check with your lender before signing a new policy to avoid any conflicts. Ask your auto insurance company if they will give you a discount, due to whatever your chosen profession is. Some companies give rate discounts to customers who work in certain fields because they feel that you are a lower risk, due to your skills or the way that you may live your life. You can protect your car, yourself, and your passengers with the right car insurance coverage. Without it, you could find yourself in serious debt should an accident occur, and possibly even on the wrong side of the law. With the knowledge you have gained from this article, you are now well prepared to look for car insurance.

Inilah Alasan Mengapa Penggaris Dibuat Hanya 30 Cm ?

welcome to my world
 
Kalau anda pernah melihat penggaris yang dipakai di sekolah dasar dan menengah, kemungkinan besar penggaris itu panjangnya 30 sentimeter. Tigapuluh sentimeter itu lebih kurang sama dengan 12 inci atau 1 kaki (foot, ini satuan panjang ala Kerajaan Inggris).
Dalam bidang komputer dan elektronika, panjang 30 sentimeter memiliki arti khusus. Arti khusus yang penting dan menjadi pegangan dalam merancang dan membangun rangkaian mikroelektronika dan rangkaian terpadu (integrated circuit, IC).

Tigapuluh sentimeter lebih kurang adalah jarak yang ditempuh oleh gelombang elektromagnetik dalam waktu satu per milyar detik. Perioda satu per milyar detik berkorespondensi dengan frekuensi 1 milyar daur (cycle) per detik (giga hertz, GHz), jadi lebih kurang pada orde/skala yang sama dengan kecepatan komputer saat ini.
Faktor 30 sentimeter menjadi penting dalam merancang sebuah rangkaian elektronika yang beroperasi pada frekuensi GHz. Dalam rangkaian elektronika skala GHz, daur arus listrik dalam rangkaian akan menghasilkan gelombang elektromagnetik yang memiliki panjang pada sekitar skala sentimeter. Jika rangkaian elektronika tersebut berukuran juga pada skala sentimeter, maka insinyur yang merancang rangkaian tersebut harus mempertimbangkan faktor waktu yang diperlukan untuk perambatan gelombang elektromagnetik dalam rangkaian.

Problem serupa, yakni memperhitungkan faktor waktu yang diperlukan untuk perambatan gelombang elektromagnetik, muncul dalam banyak teknologi sehari-hari: radar, telekomunikasi seluler dan satelit, jaringan serat optik (optical fiber), global positioning system, perpetaan, geodesi, dan banyak lagi.

Dalam fisika partikel eksperimen, problem ini muncul ketika fisikawan harus mempertimbangkan waktu tempuh sinyal dalam serat optik dari detektor yang terletak 100 meter di bawah tanah ke komputer yang membaca dan menyimpan data di permukaan tanah. Sebagai contoh, akselerator LHC beroperasi dengan frekuensi 40 MHz atau periode 25 per milyar detik. Setiap 25 per milyar detik, terjadi beberapa tumbukan/interaksi di dalam detektor. Dengan menggunakan aturan 30 sentimeter, kita tahu bahwa selama 25 per milyar detik, cahaya akan menempuh jarak 7.5 meter. Padahal jarak dari bawah tanah ke permukaan tanah adalah 100 meter lebih! Sebelum sinyal dari detektor mencapai permukaan tanah dan direkam dalam komputer, detektor sudah menerima data kembali!

Padahal detektor di bawah tanah pada umumnya memerlukan konfirmasi (handshake) dengan komputer yang terletak di permukaan: apakah sinyal/informasi yang dikirimkan sudah sampai atau belum. Dengan pertimbangan itu, maka detektor di bawah tanah dirancang untuk menyimpan sementara data-data tumbukan/interaksi partikel dalam sebuah tempat penyimpanan sementara (buffer memory). Sehingga bila karena suatu sebab kiriman informasi dari bawah tanah ke permukaan terganggu, detektor di bawah tanah akan menerima kabar dari komputer di permukaan bahwa informasi yang dikirim belum diterima, dan bisa dikirimkan kembali.

Kok bicara fisika partikel eksperimen kedengarannya seperti teknik elektro atau instrumentasi! Ini semua karena kebutuhan: untuk membangun alat eksperimen fisika partikel diperlukan kerjsama antara fisikawan dengan insinyur: baik insinyur teknik tenaga listrik, teknik elektronika, teknik mesin, teknik pendinginan, teknik komputer, teknik sipil, dll. Tanpa kerjasama tersebut, tidaklah mungkin alat dan fasilitas eksperimen fisika partikel bisa dibangun.

Catatan: Penggunaan ukuran 30 sentimeter untuk memberikan ilustrasi/gambaran tentang kecepatan cahaya dan jarak yang ditempuh, dipopulerkan oleh Laksamana Pertama (Commodore/Rear Admiral) Grace Hopper, seorang sesepuh dalam bidang komputer dan informatika.
