Konunun teknik yönü kadar, felsefi yönünün de çok zor ve pek çok tartışmayı tetikleyecek nitelikte olduğu herkezce kabul görmektedir. Bu nedenle konuya ünlü bir kaç fizikçinin kuantum hakkındaki düşünceleriyle, bu işin ne denli çetin bir ceviz olduğunu vurgulamaya çalışarak başlamak istiyorum.

Bristol üniversitesi fizik bölümünden Robert Gilmore'un, Alis Kuantum Diyarında adlı yapıtının önsözüne şu sözlere yer verilmektedir.

"Yirminci yüzyılın ilk yarısında evren anlayışımız tümüyle alt üst oldu. Eski klagib fizik kuramlarının yerini, dünyaya bakış açımızı değiştiren, kuantum mekaniği aldı. Kuantum mekaniği, yalnız eski Newton'cu mekaniğin ortaya attığı düşünceleri değil, sağduyumuzla da pek çok açıdan uyuşmazlık içindedir. Yine de bu kuramların en şaşırtıcı yanı, fiziksel sistemlerin gözlenen davranışını, önceden haber vermedeki olağanüstü başarısıdır. Kuantum mekaniğinin bize saçma geldiği anlar olabilir. Fakat doğanın izlediği yol budur. Biz de buna uymak zorundayız."

Kaliforniya Teknoloji Enstitüsünden Prf. Rıchard Feynman; kuantum mekaniği ile ilgili öğrencilere verdiği bir konferansta, konuya şu espiri ile başlıyor.

"Kuantumu anlamak gerçekten zor. Ancak gerçekte bu zorluk pgibolojik. Kendinize sürekli " ama bu nasıl olabilir " diye sormanızın yarattığı sıkıntıdan kaynaklanır. Sorduğunuz her soru, onu anlaşılmış bir şeyler cinsinden görmek arzusunun dışa vurumudur. Onu alışılmış bir şeye benzeterek açıklayacak değilim. Yalnızca açıklayacağım.

Bir zamanlar gazetelerde " Görecelik " teorisinin sadece oniki kişi tarafından anlaşıldığı yazılmıştı. Hiçbir zaman öyle bir dönem olduğunu sanmıyorum. Onu yalnız tek bir kişinin anladığı bir dönem olabilir, çünkü, daha kaleme almadan önce bu teoriyi fark eden kişiydi o. Ancak onun çalışmalarını okuyan birçok kişi Görecelik teorisini şu veya bu şekilde anladı. Buna karşın, kuantun mekaniğini kimsenin anlamadığını rahatlıkla söyleyebilirim. Bu nedenle, anlatacaklarımı gerçekten anlamanız gerektiğini düşünerek dersi ciddiye almayın; Gevşeyin ve bu işin keyfini çıkarın."

Yine ünlü bir bilim adamı, "Kuantum fiziğini anlayamazsınız, ona sadece alışabilirsiniz" diye bir yorum getirmiştir.

Erdal inönü ise, "Kuantum fiziğini anlamak için güçlü bir empatiye, yani olayları ve düşündüğünüz hipotezin deneyini kafanızda yapabilmelisiniz" demiştir.

Ve son olarak Danimarkalı ünlü fizikçi Niels Bohr; "Kuantum fiziği kafanızı karıştırmadıysa onu tam olarak anlamamışsınız demektir."diyerek, beklide bu konuya son noktayı koymuştur.
