ساعة ذرية هي الأدق في العالم

02 يوليو 2013

( ي ب أ) - أعلن أن ساعة ذرية بريطانية هي الأكثر دقة في العالم بإعطاء الوقت بعد أن أجريت عليها بعض التعديلات.

وذكرت صحيفة "التلغراف" البريطانية أن فريقاً من العلماء البريطانيين والأميركيين وجد من خلال تحليل جديد للساعة البريطانية أنها ستسقط فقط ملياراً من الثانية كل شهرين لتكون الساعة الأدق في العالم.

وتعتبر هذه الساعة المسؤولة عن المحافظة على دقة الساعات في بريطانيا، والتي تساهم أيضاً في قياس الوقت العالمي، دقيقة جداً، وهي واحدة من عدد قليل من الساعات المشابهة في العالم التي تحدد بالضبط مدة الثانية الواحدة عن طريق قياس الموجات أثناء تسببها بذبذبة ذرات السيزيوم.

وتمكن العلماء في المختبر الوطني الفيزيائي في بريطانيا، بقيادة كرزيستوف سيزيمانيك، من تقليص هامش الخطأ إلى مستويات غير مسبوقة.
