Saguna and Nirguna - both are originally Sanskrit words. They are not terms coined by modern science. Swami Dayananda Saraswati, the extraordinary scholar of Sanskrit language and Vedic philosophy, has written about these two words in his Satyarth-Prakash (The Light of Truth) as under, and made it very clear that God is both - Saguna as well as Nirguna:
Vedas say – “devasya pashya kavyam” i.e. behold and correctly study the secrets of the Vedas and the Universe. They are embodiments of God’s excellence. So it’s quite natural that we study creation in the sciences. If it is supported by appropriate logic and right conclusions, it may lead one towards true theism. But we must understand that in modern science there exists no special lesson or chapter treating the subject of God. Therefore, how can we say that God has a place in modern science?

सुपर्णयातुमुत गृध्रयातुं दृषदेव प्र मृण रक्ष इन्द्र ||
ओउम् ! विद्म ते सभे नाम नरिष्टा नाम वा असि |
ये ते के च सभासदस्ते मे सन्तु सवाचसः ||
Mark of Success.
If man is desirous of achieving success, then it would be necessary for him that he adopts some of the characteristics of animals that we see around. What are they?
है चुनाव की दौड़ ये कैसी, जिसमें बेचें सब अपनी अपनी पुड़िया
पुड़िया भी कैसी है जिसमें, विष या अमृत भरा हुआ है
